Description
XPath queries don't work with <template> tags.
The following code:
<?php
use Dom\HTMLDocument;
use Dom\XPath;
$html = '<html><body><template><p>Hello World</p></template></body></html>';
$dom = HTMLDocument::createFromString($html, LIBXML_NOERROR);
$xpath = new XPath($dom);
$xpath->registerNamespace("html", "http://www.w3.org/1999/xhtml");
$query = "//html:body//text();"
foreach ($xpath->query($query) as $text) { echo $text->nodeValue . "\n"; }Resulted in this output:
But I expected this output instead:
I understand that the new HTMLDocument implementation adheres more closely to HTML5 standards, meaning that the content of <template> tags is considered a document fragment and not part of the main DOM. However, the current workaround is cumbersome:
- Query all
<template> tags directly.
- Create separate
HTMLDocument instances for their content.
- Query the content of each
HTMLDocument individually.
This process becomes increasingly complex with nested templates. I believe this could be simplified with a flag in either HTMLDocument or XPath.
