Re: [xml] Error on parsing HTML with libxml

["Eric S Eberhard" <flash vicsmba com>]

That would be incorrect behavior for libxml2 -- as Liam and I both said -- you have to encode some how.  
CDATA is one way and URL encoding (e.g. &lt, &gt, etc).

I sent you a link.  
https://stackoverflow.com/questions/1398571/html-inside-xml-should-i-use-cdata-or-encode-the-html

Which I believe is the correct answer.  If someone else is making the XML then they should fix it.  I also 
like the "soup" answer and agree.

We have people send invalid XML to our customers all the time ... my customers have chosen to make me fix it 
:-) .  That is what I get paid for so ...

We pre-process all XML files and fix every mistake we know (and the program slowly grows) before parsing it.  
Examples include attributes without a space between the quote and start of next attribute.  It would be wrong 
for me to ask libxml2 to do this -- not on spec.  So I do it.

So if was you and you have you take the files like this -- then pre-process them and fix them with either 
CDATA or encoding because I don't think anyone else would support the kind of change you are asking for ...

I can't chage the source of the HTML page, because the page will be generated by another system, where I 
don't have access. I get only the pages from there and our Apache module makes a post-processing step just 
before the pages will be sent to the user's browser. And there I need a parser to change something within the 
page.

So I think, the libxml should not parse the content of inline scripts to handle that.

There is also a comment on

https://stackoverflow.com/questions/51892455/php-5-4-16-domdocument-removes-parts-of-javascript

which describes your idea with CDATA, but it didn't work.
