Regex to replace invalid XML string

[girishk]

I am getting an XML rss feed but i am finding invalid html tags in it. Basically the string which i receive is as below:

<channel>
<item>
<category></category>
<link>www.googl e.com</link>
<title>Google Home Page</title>
<description>Th is is a google home page</description>
<pubDate>Thu, 27 Mar 2008</pubDate>
</item>

<item>
<category></category>
<link>www.msn.c om</link>
<title>Microsof t Home Page</title>
<description>Th is is microsoft home page <hl2 </description>
<pubDate>Thu, 27 Mar 2008</pubDate>
</item>
</channel>

Note the occurance of the tag like character <hl2 in teh description TAG. Is there any regular expression out there to search for '<' chars inside the description tags. I mean i should be able to check for this tag ie '<' in all description tags in the XML string and replace that with string.Empty.

I would need the code in a .NET language.

Any help would be greatly appreciated.

Girish.

My first action would be to complain, maybe your not the only one facing this problem. Then for existing files maybe a xml validator. HTH.
