Re: [xml-dev] Error and Fatal Error

I don't buy that. And not so easy to replace '<' with

'&lt;' in just the element content and not the tags.

No, if you are taking strings from user data (and can ignore the possibility of control characters there) then the only thing you have to do is replace < by &lt's and & by &lt;, You don't need to parse anything. In a typical .net language you are talking about a line of code.

Inserting a string into XML without quoting the xml syntax characters <  and & (and it's safest to to > as well while you are there) is just generating errors that it is unreasonable to expect a parser later in the chain to fix. If you have an application generating syntax errors then surely it's better to fix the application than to expect every tool taht may consume the output of that application to somehow magically fix up the errors.
