Remove it from what? How are you getting the XML document? Show us some code, so we can figure out what you are talking about. — Oded, May 09 '10 at 08:28
You can't, not robustly. XML is not a regular language, and cannot be reliably parsed with regular expressions. http://stackoverflow.com/questions/1875258/regular-expression-to-parse-links-from-html-code/1875281#1875281 — Michael Petrotta, May 09 '10 at 08:29
How do you identify which tags you want to remove and which you wish to keep? — Mark Byers, May 09 '10 at 08:30
i know them for advance. i can do it with alot of regexs each one for each tag... i don't care... — John, May 09 '10 at 08:31
@John: But if you don't tell us how to identify which tags you want to remove, it's very difficult to give a specific answer. I can only give a starting point. — Mark Byers, May 09 '10 at 08:35

I'd advise against regular expressions for this task.

However you can use LINQ to XML to remove tags with name "aaa" like this:

XDocument doc = XDocument.Load("input.xml");
doc.Descendants("aaa").Remove();
doc.Save("output.xml");
