html parser simple dom 1

[someoneneedshelps]

Does anyone know anything about simple dom parser? I'm look at a problem with the find function[pre]foreach($html->find('span itemprop="name"') as $cat)
echo $cat->src;[/pre]

even though there is only one instance I get more after it>? how do I get first instance

Not sure what you are attempting to return with itemprop="name".

If you want to specify a span with a property named "itemprop" that has a value of "name", you can do something like:

foreach($html->find('span[itemprop=name]') as $cat)

if you are looking for a span that has a property named "name" with any value, then:

foreach($html->find('span[name]') as $cat)


beyond that, spans don't have src attributes so doing $cat->src will return nothing. Using the "plaintext" option instead will return the text inside the span.

foreach($html->find('span[name]') as $cat)
echo $cat->plaintext;

This might also help:

thanks will try it, the text i want is inside

<span itemprop="name">

... can i also ask, why does'nt simple dom let you put stuff into an array?

foreach($html->find('img')as $img)
   $items[]=$img->src;

print_r ($items);

this one worked for reference to this thread,

foreach($html->find('span[itemprop=name]') as $cat)

I cant understand why I have to dismantle the html page source into something different

I'm getting there BUT... if I have a number of th elements condition as a title is one of them, what is the find() on that please? inside the html elements is this src or name?

You mean your html is something like: <th title="somethinghere">?

If so just use the same general structure:

$html->find(th[title]);

This looks for th tags that have a title attribute or property.

Only image tags and iframes have a "src" attribute. ( <img src="path/to/img">, <iframe src="path/to/file.html"> ) So only if you are trying to get the image's or iframes path would you use "src". If you are trying to get the contents of any other HTML element, use "plaintext".

... can i also ask, why does'nt simple dom let you put stuff into an array?

It does.

For non image elements this works for me:
$myarray[] = $element->plaintext;

I cant understand why I have to dismantle the html page source into something different

Not sure what you mean. If you are looking for a specific element then you need to tell the find() function what it is. You are not dismantling anything, you are specifying what you are looking for in a way that makes sense to the dom parser.
