php DomDocument->saveHTML removes slash

Question

Just the part that confuses me:

<?php
echo "Start\n";
$newdoc = new DOMDocument();
$newdoc->loadHTML("<script>document.write('</scr' + 'ipt>');</script>"); 
echo $newdoc->saveHTML();
echo "\nDone\n";

It will output:

<script>document.write('' + 'ipt>');</script>

Why does it do that and how can I avoid it?

Answer 1

You have to escape the slash:

$newdoc->loadHTML("<script>document.write('<\/scr' + 'ipt>');</script>");

• revo: Backslash remains in the results.
• thefallen: @revo what do you aim to achieve with this exactly?
• revo: I'm not going to achieve something but you should have noted what I already commented. Also you can't do such escaping within a large HTML input so it's totally a temporary solution.
• thefallen: @revo I thought your comment was from the author of the question so I was wondering why is he doing this. Sorry for the misunderstanding.
• revo: No problem @TheFallen
