php - How do you access Simple DOM selectors? -

i can access of 'class' items a

$ret = $html->find('articleinfo'); , print first key of returned array. 

however, there other tags need span=id"firstarticle_0" , cannot seem find it.

$ret = $html->find('#span=id[ etc ]'); 

in cases returned, it's not array, or array empty keys.

unfortunately cannot use var_dump see object, since var_dump produces 1000 pages of unreadable junk. code looks this.

<div id="articlething">      <p class="byline">by lord byron , <a href="www.marriedtothesea.com">alister crowley</a></p>      <p>      <span class="location">georgia mountains, canada</span> |      <span class="timestamp">fri apr 29, 2011 11:27am edt</span>      </p>  </div>  <span id="midpart_0"></span><span class="mainparagraph"><p><span        class="midlocation">tuscaloosa, alabama</span> - invented cheese? wants know. held big meeting. tom cruise scientologist. </p>   </span><span id="midpart_1"></span><p>the president , family visited chuck-e-cheese in morning </p><span id="midpart_2"></span><p>in russia, 900 people lost in balls.</p><span id="midpart_3"> 

simple html dom can used find span specific class.

if want span's class=location then:

// create html dom $html = file_get_html($iurl);  // text elements $aobj = $html->find('span[class=location]'); 

then like:

foreach($aobj $key=>$ovalue) {    echo $key.": ".$ovalue->plaintext."<br />"; } 

it worked me using example output was:

label=span, class=location: found 1

0: georgia mountains, canada

hope helps... , please simple html dom great , easy use once hang of it. keep trying , have number of examples use on , on again. i've scraped pretty crazy pages , easier , easier.
