如何在使用DOMDocument时将文本内容分隔为<BR>

Question

I have a page full of elements Im trying to parse. I want class1 and class2 as seperate text. However, class 2 exists inside class1. So if I do textContent, it retrieves all the text.

Heres the structure...

 <div class='class1'> 
     Name <br/> <span class='class2'>Other Name</span>
  </div>

If I do this...

 $dom = new DOMDocument();
 $dom->loadHTMLFile($url);
 $finder = new DomXPath($dom);
 $classname="class2";
 $nodes = $finder->query("//*[contains(@class, '$classname')]");
 foreach($nodes as $n){
     echo $n->textContent;
 }

I can get the class2 elemtn just fine. But if I do the same for class1. I get the textContent of class1 which also includes the contents of class2.

How can I extract these seperately?

Answer 1

In your example, $n contains 5 child nodes:

1. "Name"
2. "<br/>"
3. " "
4. "<span class='class2'>Other Name</span>"
5. " "

The property textContent consist of the text of this node and all its descendants. To access the content only of the first child use:

echo $n->firstChild->textContent;
