Parsing FCPXML in PHP

Using PHP I'm trying to figure out how to parse a Final Cut Pro X XML file, which seems to be different than standard XML, and have had no success so far. Ultimately I need to more finely tune the results but for now, just getting any results would be helpful! This gives nothing useful even though it seems to work on other XML files:

Code: 
<?php
 $xml = simplexml_load_file("filename.fcpxml");
echo $xml->getName() . "<br />";
foreach($xml->children() as $child) {
   echo $child->getName() . ": " . $child . "<br />";
   }
 ?>

Has anyone worked with FCPXML who can offer help? It is mainly the <title> area I want to fetch but getting any results is a good start. Ideas?

Thanks.

Don

Can you show s an example of kind of file you are working with?

Even if we haven't directly used FCPXML, we may be able to help you get the contents if we knew the file structure.

Yes, I was just about to do just that. Basically I am trying to come up with some output that is usable outside of Final Cut Pro X in an SRT type format (file format used for video subtitles) so what I am really after isn't the entire file. I need only the portions between the title tags where the role="Subtitles" along with the text, offset, duration and start values:

Code: 
<title lane="6" offset="3671668/60000s" ref="r6" name="Some text here," duration="412412/60000s" start="215999784/60000s" role="Subtitles">
<adjust-transform position="0.267518 -32.3158"/>
<text>Some text here," </text>
</title>

<title lane="6" offset="4130126/60000s" ref="r6" name="more text," duration="288288/60000s" start="216003788/60000s" role="Subtitles">
<adjust-transform position="0.267518 -32.3158"/>
<text>more text,</text>
</title>

There are other title tags without role="Subtitles" or with no role at all but I do not need those. The actual format needed is somewhat specific and I am totally unclear now how to convert the start, offset and duration to values I can actually use but this is what the end result should look like in general:

Code: 
1
00:00:11,000 --> 00:00:15,000
Some text here,
 
2
00:00:50,000 --> 00:00:56,000
more text

If the general output can be done something like this, I can research to try to find out how to do the conversion to the time format needed for the beginning and ending of each one so any help to get started is appreciated.

I was referring to the general layout of the file itself. What context the <title> tags are in. Not just how the title tags look.

XML parsing at its most basic turns each tag into an object. The tag properties become array keys of the main object. While contents take on their general structure. If there more tags inside its an object each tag becomes an additional object. If its text its a standard string.

So for instance

An XML file like this:

Code: 
<fcpxml version="1.0">
<project name="MyProject">
<!-- Project Resources -->
<resources>
<title lane="6" offset="3671668/60000s" ref="r6" name="Some text here," duration="412412/60000s" start="215999784/60000s" role="Subtitles">
<adjust-transform position="0.267518 -32.3158"/>
<text>Some text here," </text>
</title>

<title lane="6" offset="3671668/60000s" ref="r6" name="Some text here," duration="412412/60000s" start="215999784/60000s" role="Subtitles">
<adjust-transform position="0.267518 -32.3158"/>
<text>Some text here," </text>
</title>

<title lane="6" offset="3671668/60000s" ref="r6" name="Some text here," duration="412412/60000s" start="215999784/60000s" role="Subtitles">
<adjust-transform position="0.267518 -32.3158"/>
<text>Some text here," </text>
</title>

<title lane="6" offset="4130126/60000s" ref="r6" name="more text," duration="288288/60000s" start="216003788/60000s" role="else">
<adjust-transform position="0.267518 -32.3158"/>
<text>more text,</text>
</title> 

<title lane="6" offset="4130126/60000s" ref="r6" name="more text," duration="288288/60000s" start="216003788/60000s">
<adjust-transform position="0.267518 -32.3158"/>
<text>more text,</text>
</title> 
</resources>
<!-- Project Story Elements -->
<sequence format="r3">
<spine>
<video ref="r2" duration="5s">
<audio lane="-1" ref="r2" duration="5s"/>
</video>
</spine>
</sequence>
</project>
<project name="Project2">
<resources>
<title lane="6">
<text>This is my title</text>
</title>
</resources>
</project>


Can be parsed to obtain the title tags of a project within like this:

Code: 
foreach($xml->children()->project->resources->title as $title) 
{

   if(isset($title['role']) && $title['role'] == 'Subtitles')
   { 
	echo $title['name'] . "<br/>" . $title['role'] . " ," .  $title['duration'] . "," .  $title->text . "<br/>" ;
   }
}

If you have more than one project, and you need title tags from each project, then perhaps:

Code: 
foreach ($sml->children()->project as $project)
{
   foreach($project->resources->title as $title)
   {
     echo $project['name'] . "," . "$title['name'] . "," . $title['role'] . "," . "$title['duration'] . "," . "$title->text . "<br/>";
   }
}

Thanks for the ideas! I tried to simplify my question but if it helps to see the entire FCPXML, it is below.

It seems I need only the start, duration and text and from there, I should be able to come up with the formatted output. I do somehow need to number sequentially each one too and some of the text contains line breaks that need preserving.

Code:

If you are familiar with the sizzle
Selector 'language' as employed in jquery and elsewhere then you can use phpquery to grab different bits of your XML. These is a performance overhead but not major. Phpquery acts as a neat abstraction layer to the XML functions (which I often find unhelpful when I don't know the precise dom structure in advance)

This is a tool that I'll be using primarily locally (here on my development system) for the times when I am working on video DVD authoring.

In the meantime, I've tried the code below but get a server 500 error as I wasn't sure if the $xml variable was to be the path to the file or the file's contents.

Code: 
$xmlUrl = "LIVE in City.fcpxml";
$xml = simplexml_load_file($xmlUrl);

foreach($xml->children()->project->resources->title as $title) 
{

   if(isset($title['role']) && $title['role'] == 'Subtitles')
   { 
	echo $title['name'] . "<br/>" . $title['role'] . " ," .  $title['duration'] . "," .  $title->text . "<br/>" ;
   }
}

Look at the structure, your title tags aren't inside resources, they are inside <clips> which are inside <spines> inside <sequence>

The key to parsing xml is the structure.

If you understand the structure you can access the contents.

$xml should be the result of either using the simplexml_load_file, or of creating a new xml object using the xml class.

This is correct:
$xml = simplexml_load_file($xmlUrl);

Once you have the xml loaded into the variable, you can start to parse.

For instance if I wanted to get the names of the clips inside audition:

Code: 
foreach($xml->children()->project->sequence->spine->audition->clip as $clip)
 {
	echo $clip['name'] ." <br/>"; 
 }

In your case the titles are inside clips inside spines inside other clips etc....

The parsing can get a little complex, but you'll need to play around with the objects to get the data out.

You are probably going to need nested foreach loops to get the data from the different spines, and clips out.

You can use the print_r function to print out the contents of an array or object so you know what the underlying structure is like. And you can construct the parser as you go.

Thanks! Your sample actually gives some results even though they are for other tags:

Code: 
Live In City MERGED-quicktime
 City opening credit frame 2
 City opening credit frame 2 - copy 1

Although I understand XML in general, it's been several years since I've worked with it and never on a file as seemingly non-standard as this. To try to better understand the structure, I found some code that appears should help but it gives no results (I didn't write it):

Code: 
function parseTree($tree, $root = null) {
    $return = array();
    # Traverse the tree and search for direct children of the root
    foreach($tree as $child => $parent) {
        # A direct child is found
        if($parent == $root) {
            # Remove item from tree (we don't need to traverse this again)
            unset($tree[$child]);
            # Append the child into result array and parse its children
            $return[] = array(
                'name' => $child,
                'children' => parseTree($tree, $child)
            );
        }
    }
    return empty($return) ? null : $return;    
}

function printTree($tree) {
    if(!is_null($tree) && count($tree) > 0) {
        echo '<ul>';
        foreach($tree as $node) {
            echo '<li>'.$node['name'];
            printTree($node['children']);
            echo '</li>';
        }
        echo '</ul>';
    }
}

$xmlUrl = "LIVE in City.fcpxml";
$xml = simplexml_load_file($xmlUrl);

$result = parseTree($xml);
printTree($result);

using phpquery I used the following code

Code: 
<?php
require_once 'phpQuery.php';
phpQuery::newDocumentFileXML('NewFile.xml');
foreach(pq('project') as $project):
	echo "Project name is " . pq($project)->attr('name') . "</br />";
	foreach(pq($project)->find('clip') as $clip):
		echo 'clip found.  Details follow:';
		echo '<br/>----------------------------<br/>';
		$t = pq($clip);
		echo 'Start Time: ' . $t->attr('start') . "<br/>";
		echo 'Duration: ' . $t->attr('duration') . "<br/>";
		echo 'Name:' . nl2br(htmlspecialchars($t->attr('name'))) . "<br/>";
		echo '<br/>----------------------------<br/>';
	endforeach;
endforeach;
?>
against a slightly modified version of the xml you posted above. the modifications:
1. finalised the unfinalised xml elements.
2. converted the & signs to the character refeferences to make valid xml.

anyway, using the above code I received the following results. Hopefully this is sufficient to evidence the usefulness of phpquery in approaching and traversing dynamic xml

Code:

if you are after a different subset of data, and can't work out how to get hold of it, post back.

phpquery is found here

Thanks, that is quite helpful! Seeing it in a tree format would help even more but in the meantime I want to post an update. I have created a simple bit of code that seems to get the title tags without getting those that are not subtitles. I understand the hierarchy of standard XML but, as pointed out, this one seems to have subsections that also contain needed data. My code so far seems to grab only the first one although examining the XML seems to show others on the same level. Since I don't quite understand it, I've limited my code to only a single loop but maybe you see something I'm obviously missing.

Having said that, this code has the hierarchy hard-coded but I am hesitant doing it that way because it will then be usable only on this one file. Another might be quite different (although the tag names will be the same) so is there a way to do it where it will just find the title tags without specifying where they are in the hierarchy?

Code: 
<?php

$xmlUrl = "LIVE in City.fcpxml"; // XML feed file/URL
$xml = simplexml_load_file($xmlUrl);

echo "<pre>";

$i = 1;
foreach ($xml->children()->project->sequence->spine->clip->title as $title) {
   if (isset($title['role']) && $title['role'] == 'Subtitles') {
	echo $i++ ."\r";
	echo $title['start'] ." --> "; 
	echo $title['duration'] ."\n";
	echo $title->text . "\n\n";
   }
}

echo "</pre>";
?>

This does not have any time conversions yet but it is otherwise giving me the results in the format I need:

Code: 
1
216073858/60000s --> 220220/60000s
will now sing

Probably best to define what you require and how you require it.
Then work out how to achieve that.
The data is all there. Extracting it is very straightforward. But extracting it correctly is hit and miss until you define the parameters and format you require.
Flat file vs tree is simply how the array is built. But as the format appears to allow arbitrary depth of clips if you do have the output as a tree you will still need to built procedural code to parse that tree to an arbitrary depth. Hence back at square one.
Try posting the problem you are trying to solve as a statement of business logic rather than coding challenge.

Oddly, I posted these thanks along with the semi-final code but it seems to have disappeared! I really appreciate the help. Thanks also for your tips on posting a question. I don't have a business mind, though, so unfortunately that would be an added challenge to post that way.

I have it working and presenting the data exactly as I need it to do by leveraging the tree code above and some of my own. It is pulling out everything needed and nothing not needed but I can't figure out how to get it to show me the <text></text> value rather than the name= value. They are usually, but not necessarily always, the same so it's important to get the <title> itself just to be sure and they must be raw, exactly as they are in the XML. Any last thoughts?

Code: 
<?php

echo "<pre>";
$xmlUrl = "LIVE in City.fcpxml"; // XML feed file/URL

$i = 1;

require_once 'phpQuery.php';
phpQuery::newDocumentFileXML($xmlUrl);
foreach(pq('project') as $project):
	foreach(pq($project)->find('title') as $title):
		$t = pq($title);
   		if ($t->attr('role') == 'Subtitles') {
			echo $i++ ."\r";
			echo $t->attr('start') . " --> ";
			echo $t->attr('duration') . "\n";
			echo $t->attr('name') . "\n\n";
			//echo $t->attr->text . "\n\n";
		}
	endforeach;
endforeach;

echo "</pre>";

the inner value of an element can be obtained just like jQuery
Code: 
pq('text').text();

or if you want the inner value together with child nodes use
Code: 
pq('text').html();

Thanks! I've always done all my programming manually without use of jQuery or phpQuery but am finding from this experience what I've been missing.

That said, your idea for pq('text').text(); looks to be exactly what I need but it seems to give a server 500 error and I'm not sure why.

Code: 
$i = 1;

require_once 'phpQuery.php';
phpQuery::newDocumentFileXML($xmlUrl, $charset='utf-8');
foreach (pq('project') as $project):
	foreach(pq($project)->find('title') as $title):
		$t = pq($title);
   		if ($t->attr('role') == 'Subtitles') {
			echo $i++ ."\r";
			echo $t->attr('start') . " --> ";
			echo $t->attr('duration') . "\n";
			echo pq('text').text() . "\n\n";
		}
	endforeach;
endforeach;

Also, the original file has carriage returns in the text tags that seem to be getting replaced by a space. Normally I would use the nl2br() PHP function to fix it but in this case it seems to be that it is an actual space being added rather than just simply a hidden \n or \r so I worked around it by using (space needed to make it show up here)

Code: 
echo str_replace("  ","& #10;", $t->attr('name')) . "\n\n";

but this does not seem to be a good fix even though it works after a fashion. The original file does have the carriage returns so are there any switches of parameters to preserve them?

Thanks again.

my bad. i gave the jquery object notation and not the php object notation.

you will need
Code: 
pq('text')->text();

however your code above won't do what you want it to as it will look at all the text nodes in the currently specified 'document'.

something like this should work

Code: 
foreach(pq($project)->find('title') as $title):
    $t = pq($title);
    if ($t->attr('role') == 'Subtitles'):
	echo $i++ ."\r";
	echo $t->attr('start') . " --> ";
	echo $t->attr('duration') . "\n";
	echo count($t->find('text')) > 0 ? htmlspecialchars($t->find('text')->text()) ? 'No text node';
        echo "\n\n";
    endif; 
endforeach;

i have not tested this code and it may be that the ->find() method does not return a true array, in which case the count function may not work as expected. but anyway the point is that you need to be looking for the node within the snip that you have, thus use ->find().

Thanks for the clarification and you're right that

Code: 
pq('text')->text();

gives all the text nodes and not just those within the conditional.

Although this

Code: 
echo count($t->find('text')) > 0 ? $t->find('text')->text() ? 'No text node';

gives a server 500 error, I've looked through the phpQuery documentation in order to try to understand it better and your count and ->find() comment helped in that direction. It works with this and even no longer seems to be losing the carriage returns now that it's getting the proper 'text' values rather than the 'name' values:

Code: 
foreach (pq('project') as $project) {
	foreach(pq($project)->find('title') as $title) {
		$t = pq($title);
   		if ($t->attr('role') == 'Subtitles') {
			echo $i++ ."\r";
			echo $t->attr('start') . " --> ";
			echo $t->attr('duration') . "\n";
			echo $t->find('text')->text() . "\n\n";
		}
	}
}

One thing I should clarify is that I am currently outputting this to the browser just for the sake of testing but ultimately the output will be to a .SRT file, which is a text file used in some DVD authoring applications for the subtitles. Since it needs to be plain text, I don't think I need to use the htmlspecialchars() function because there can be no HTML in it.

I still need to try to come up with formulas for the 'start' and 'duration' values but that's unrelated to the problem here (although I don't see a Final Cut Pro forum on tek-tips), which now seems to have been solved.

Thanks to all who helped!

Thanks, yes, I discovered that after posting. I have it working as needed with the code I posted above but this:

Code: 
echo count($t->find('text')) > 0 ? $t->find('text')->text() : 'No text node' . "\n\n";

seems to strip out all line breaks. Anyway, as it's working now, there is no need to solve this issue but thank you for pointing out the error.

it should not strip out the line breaks, but might strip out html entities like <br/>. If you want the raw content then change ->text() for ->html()
