XSLT can only handle well-formed XML documents, so you need to fix the
problem at the point where you are generating XML: that is, in your php
function. In fact, it goes without saying that if you have code that
attempts to generate XML, it should always generate well-formed XML.

> Hi all,

> Is there a way to handle/discard invalid characters?

> Problem:
> I have to use data from several different sources that have 
> different/unknown encoding types.  I store all of them in a 
> MySQL db using ISO-8859-1 encoding.  A php function grabs the 
> data and fits it into XML format.  When I use the XML file as 
> input to an xsl transform, I get "Invalid character 
> (character code 25) detected".

> Possible solutions:

> 2) Delete all the invalid characters
> 3) Display them as gibberish in my documents
> 4) Basically anything that won't cause an error and will let
