change xpath code to get correct info php curl

change xpath code to get correct info php curl

okay so i have a script that use the following source code
<h4>
<label id="ct0_l00_PageContainer_MyContainer_sym" for="symbol">
%
</label>59</h4>
my xpath code is
$dom = new DOMDocument();
@$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$value =
$xpath->query('//label[@id="ct0_l00_PageContainer_MyContainer_sym"]/following-sibling::text()')->item(0)->nodeValue;
this query worked fine but after changing a few bits it no longer works i
have the new source code wich is below
<div id="ctl0_PageContainer_Container_divSummary">
<div class="blueheaderbar">
<h2>

</div>
<div class="usesummary">
