简单的html dom解析器获取值

I am using simple_html_dom.php

How to get following data

<td class="t-loss">% Change<strong>-10.75</strong></td>

I want to get -10.75 t-loss occurs only once in html code

<p class="data" id="bseVolume">22,621</p>

I want to get 22,621 bsevolume occurs only once in html code

please let me know what code should I use.

edit more info:

$bseVolume = $content->find("//p[contains(@class, 'data')]"); 

class : data appears multiple times in html but id="bseVolume" appears only once.
I tried

$vaue1 = $html->find("//p[contains(@id, 'bseVolume')]"); 
$volume1 = $bseVolume1[0]->innertext; echo $volume1 ; 

The result is blank. Can you comment?

You can use Simple HTML DOM find to find the <td> or <p> elements.

From the docs:

Find (N)th anchor, returns element object or null if not found (zero based)

$ret = $html->find('a', 0);

You could find the <p> you are looking for like this:

$bseVolume = $html->find("p[id=bseVolume]", 0);
echo $bseVolume->innertext();

You could find the <td> you are looking for like this:

$tLoss = $html->find("td[class=t-loss] strong", 0);
echo $tLoss->innertext();
