如何在html标签之间添加文本

Question

I want to add a string in between html tags in php. I'm using php's dom document class and you can only add strings inside html. Here is an example of what I am trying to accomplish

<tag>example</tag><another>sometext</another>

I want to add a string in-between these two tags so it should look like

 <tag>example</tag>STRING<another>sometext</another> 

I want to be able to seperate these tags so I can use the explode function to split every tag in the html page to an array then traverse them for later use.

Answer 1

You can add a textnode without being or having a tag.

$doc = new DOMDocument();

$tag = $doc->createElement('tag');
$doc->appendChild($tag);
$tag->appendChild($doc->createTextNode('example'));

$node = $doc->createTextNode('STRING');
$doc->appendChild($node);

$another = $doc->createElement('another');
$doc->appendChild($another);
$another->appendChild($doc->createTextNode('sometext'));

echo $doc->saveHTML();

will give

<tag>example</tag>STRING<another>sometext</another>

Answer 2

You need to connect php and html. Exemple:

<?php echo "<tag>example</tag>.'STRING'.<another>sometext</another> " ?>
