Getting Div's value from a File/String/URL

hiya guys,

Before asking question let me tell you i am really bad at regular expressions (REGEX) :(

Well to start with, i want to get the value inside a div with a particular id.
An example can be

Expand|Select|Wrap|Line Numbers

	<div id="static">

This is the content i want to fetch, When i have this whole file in the string format which i got it from file_get_contents

</div>

I hope i made my question clear, please let me know how can i do that ?

Thanks :)
Cheers !!

Markus

Re: Getting Div's value from a File/String/URL

Would

Expand|Select|Wrap|Line Numbers

preg_match('/<div id=\"".$id."\">(.*?)</div>/', $string, $matches);

Work?

Re: Getting Div's value from a File/String/URL

well writing this would give me error,

Expand|Select|Wrap|Line Numbers

	preg_match('/<div id=\"normal\">(.*?)</div>/', $getWholePage, $matches);
 
Warning: preg_match() [function.preg-match]: Unknown modifier 'd' in D:\xamp\htdocs\cut\index.php on line 14

preg_match('/<div id=\"normal\">(.*?)</div>/', $getWholePage, $matches);

The delimiter is a forward slash, so you need to escape it in the closing div tag.

preg_match('/<div id=\"normal\">(.*?)<\/div>/', $getWholePage, $matches);

Re: Getting Div's value from a File/String/URL

Although this is the PHP forum, so my post does not really belong here, I'd like you to consider a JavaScript solution (since you do not want to use a regexp). See this sample

Expand|Select|Wrap|Line Numbers

	<div id="static">

This is the content i want to fetch, When i have this whole file in the string format which i got it from file_get_contents

</div>

<script type="text/javascript">

if (document.getElementById("static").firstChild.nodeName=="#text")

alert ('The div text is: '+document.getElementById("static").firstChild.nodeValue);

</script>

but will this script work for a string ??
As i mentioned i am getting a file contents using PHP function..
I guess JS works on browser and when the current page is loaded..
Say if i am on page X i want to get the contents of a div which is stored in varibale $str.
Is that possible using JS ??

	<?php

$str='<div id="static">This is the content i want to fetch, When i have this whole file in the string format which i got it from file_get_contents</div>';

?>

<div id="myId" style="visibility: hidden;">

<?php

echo $str;

?>

</div>

<script type="text/javascript">

if (document.getElementById("static").firstChild.nodeName=="#text")

alert ('The div text is: '+document.getElementById("static").firstChild.nodeValue);

</script>

But when the above is not what you are looking for then I don't understand your problem and, in that case, please elaborate a bit more.

I really don't know what you want to achieve or why. But assuming the complete div is in a PHP variable $str and you wanted to get only the 'between' div's text from that php variable using JS. In order to prevent passing the PHP variable to JS, I would show the div (from the variable) within another div with visibility=hidden and run the JS. Like this[php]<?php
$str='<div id="static">This is the content i want to fetch, When i have this whole file in the string format which i got it from file_get_contents</div>';
?>
