Illegal Charcters in XML feed iamvela msg:3698692 9:16 am on Jul 15, 2008 (gmt 0) I have an XML feed that is based upon text submitted by users, however every so often users submit characters taht are illegal for XML causing the entire feed to choke :(
I need some help in filtering out (brute force replace is ok) these ilegal characters.

Whatever script you are using to parse the feed is what you need to replace the characters. For example, with PHP you can use str_replace(). I, on the other hand, would run the XML through W3C's validator service to see if it is valid XML before using it--if not then show an alert of some kind. httpwebwitch msg:3698880 2:36 pm on Jul 15, 2008 (gmt 0)
you can either pasteurize the text to remove/replace those characters, or you can wrap them in a special CDATA placenta.
So, for instance:
<title>The Big Book of <XML> & &agrave;cc&eacute;nted char&agrave;ct&egrave;rs</title> </book>
<title><![CDATA[The Big Book of <XML> & àccénted charàctèrs]]></title> </book>
the CDATA is a far better solution

FYI regarding CDATA: [ ...] w3schools.com
Unless you know that the user-entered data is safe, like it's only EVER going to be an integer or alphanumeric string, then treat it as CDATA and encapsulate it accordingly.
