Why am I still getting an exception when I do this:

libxml_use_internal_errors(true);
$this->xml = new SimpleXMLElement($this->htmlString);

or this
$this->xml = new SimpleXMLElement($this->htmlString,
LIBXML_NOERROR|LIBXML_NOWARNING);

?

The exception says "Exception: String could not be parsed as XML". Not
a hint of why not, of course.

I thought the point of those things was to just stuff the content in,
and let user code handle errors? I mean, I *know* the provided HTML is
broken. I also know there's not a chance in hell of it ever being
fixed (completely out of my control).

And yes, I'd rather use DOM, but I can't.

The XML needs to be "well formed" [1]. So, if it is junk, you can't
read it using SimpleXML as the XML is not well formed.

Try putting it through Tidy first - that is, tidy the file first.

I thought so, thanks. What does libxml_use_internal_errors do then, if
it doesn't allow me to handle those problems in my own code?

I'm trying to just use xml_parse and so on now.

This problem really should be *so* easy. In fact I've already solved it once X(

Ha ha!

Sorry.

It's almost certainly not available. I don't want to talk about it
*cries*

Hi Gary,

I have code that looks like this:

libxml_use_internal_errors(true);
$xml = simplexml_load_string($val);
$errors = libxml_get_errors();

if ($errors)
do this
else
do that

which works fine. Not sure if that's helpful to you, but it seems
like it might.

Yeah. I tried simplexml_load_string and found that "worked" (in that it
didn't cause an exception - there are errors which caused the conversion
not to work). I wonder what the difference is between doing "new
SimpleXMLElement" and calling simplexml_load_string which results in the
libxml_use_internal_errors call being ineffective. Odd.
