Link to image in CDATA

pknudsen · Nov 5, 2010

In my XML-code I want to make a link to popup an image.

I have this code:
the data comes from this array:
$files[] = array(
"filename"=>$file,
"intLatitude"=>$intLatitude,
"intLongitude"=>$intLongitude);
"directory"=>$$dh;
------------------
-and the XML-file:

$picfil = $dir."/".$name;
$file = fopen($dir."/".$name,"w");

$xml = '<?xml version="1.0" encoding="UTF-8"?>';
$xml .= '<gpx>';
$xml .= '<metadata>';
$xml .= '<extensions>';
$xml .= '</extensions>';
$xml .= '</metadata>';
for($i = 0; $i < sizeof($files); ++$i) {
$xml .= '<wpt lat="' . $files[$i]['intLatitude'] .'" lon="' . $files[$i]['intLongitude'] .'">';
$xml .= '<extensions>';
$xml .= '<html>';
$xml .= '<![CDATA[<a href="#"><img src="'.parseToXML($files[$i]['filename']) .'"/></a>]]>';
$xml .= '</html>';
$xml .= '</extensions>';
$xml .= '</wpt>';
}
$xml .= '</gpx>';
fwrite($file,$xml);
fclose($file);

-and the function parseToXML

function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','<',$htmlStr);
$xmlStr=str_replace('>','>',$xmlStr);
$xmlStr=str_replace('"','"',$xmlStr);
$xmlStr=str_replace("'",''',$xmlStr);
$xmlStr=str_replace("&",'&',$xmlStr);
return $xmlStr;
}

I want to change the CDATA-code so I can open the image in an popup-window. The images is in different directories, so the must be a variable.

[0] Let me set-aside any doubt in regard to the construction of $xml. I take it as correct to your satisfaction (including typos that may not exist in the script, $file at multiple places, or what to result of a pass-through of the function parseToXML().)

[1] >I want to change the CDATA-code so I can open the image in an popup-window.
As to this functionality, it belongs to html arena. It won't happen in the xml document as reflect in $xml.

[1.1] Having said that, you can extract the cdatasection as child of every possible <html> element. Put them all inside a html wrapper element, and then save it to a html file. In that case you can do the hyperlinking. (But then again just a remark: the href attribute is set to #. Hence, I don't see, a priori, the effect of clicking on the image bringing you to some other url. In any case, it doesn't matter and I leave it to you for further setup.)

[1.2] This is how it can be done as a quick sketch.
[tt]
[green]//etc etc in your script before the end
fclose($file);[/green]

//now your desired output html file
[green]$htmlfile="xyz.htm";[/green]

$xdoc=DOMDocument::loadXML($xml);
$xpdoc=new DOMXpath($xdoc);
$anchors=$xpdoc->query('//html');

$s='';
foreach ($anchors as $a) {
$s.=$a->nodeValue."\n"; //no need to pass through any function like parseToXML
}
$s="<html>\n<body>\n".$s."</body>\n</html>";

$f=fopen($htmlfile,"w");
fwrite($f,"\n\n");
fwrite($f,$s);
fclose($f);
[/tt]
[1.3] Now you have a html file which has the rudimentary layout that gives you the desired hyperlinkage.

I suggest i should replace my CDATA with something. Can you explain me?

If I replace my code in CDATA with text:

$xml .= '<![CDATA[<a target=_blank href="mymap/picture.jpg"><img src="mymap/picture.jpg"/></a>]]>';
-then it works.

I should say: what I need is a output like this:

example:

<?xml version="1.0" encoding="UTF-8" ?>
- <gpx>
- <metadata>
- <extensions>
</extensions>
</metadata>
- <wpt lat="55.68316" lon="11.82938">
- <extensions>
- <html>
- <![CDATA[ <a target=_blank href="mymap/picture.jpg"><img src="mymap/picture.jpg/></a>
]]>
</html>
</extensions>
</wpt>
</gpx>

If you can replace like that, then you can replace until any thing works for you in any manner you like. That's not my problem.
