parsing - Using xPath & PHP to loop through an HTML and extract required attributes & text? -


i trying use php , xpath extract various text , attributes html file.

the desired output this:

 item1 | level1 = aaaa | level 2 = aaa.com | text

i can construct xpath trouble creating necessary loops cycle through file. what best method this?

sample html - sections , subsections (item 1 item 999):

 <div class=container1>     <div class=item1>            <div class=level1>                <h1>aaaa</h1>           </div>            <div class=level2>                <a href=aaa.com>text</a>                <p>text</p>           </div>      </div>             ..      <div class=item2>            ..   </div>

i've embedded xml , used loadxml() instead of load().

please notice bit ambigous, "text" mean after href, text href <a href=aaa.com>text</a> or text <p>text</p>. solution uses text href.

output

item1 | level1 = aaaa | level2 = aaa.com | atext1

item2 | level1 = bbbb | level2 = bbb.com | btext1

solution

<?php  // file $xml = ' <div class="container1">   <div class="item1">     <div class="level1">       <h1>aaaa</h1>     </div>     <div class="level2">       <a href="aaa.com">atext1</a>       <p>atext2</p>     </div>   </div>    <div class="item2">     <div class="level1">       <h1>bbbb</h1>     </div>     <div class="level2">       <a href="bbb.com">btext1</a>       <p>btext2</p>     </div>   </div> </div> ';  $xmldoc = new domdocument(); //$xmldoc->load('yourfile.html'); $xmldoc->loadxml($xml);  $xpath = new domxpath($xmldoc);  foreach($xpath->query("//div[contains(@class,'item')]") $node){      echo $node->getattribute('class') . ' | '; // item 1      $div = $node->getelementsbytagname('div');     foreach($div $i) {          if($i->getattribute('class') === 'level1') {             echo $i->getattribute('class') . ' = ' . $i->nodevalue . ' | ';         }          if($i->getattribute('class') === 'level2') {              echo $i->getattribute('class') . ' = ';              foreach($i->childnodes $node){                 if($node instanceof domelement && $node->hasattribute('href')) {                     echo $node->getattribute('href') . ' | ' . $node->nodevalue;                 }             }         }     }      echo '<br>'; }  // item1 | level1 = aaaa | level 2 = aaa.com | text2 ?>
