XML File Parsing

[DonCL]

Hello, i need to write a console app that will search a folder and subfolder for 1 or more files of a given filename. for each file that is found, the XML file must be parsed for a substring in the <url> element, and replace it w/ another substring. in other words, for each <url> tag found in the XML file i am using (the name of the file is TNT.XML), search for a substring and replace it w/ another. I would appreciate any help. Thanks in advance.

how about the XmlReader and XmlWriter classes? The weevil of doooooooooom

i need to use the system.xml and system.io reference libraries that can be linked to the c# console.

If all you're doing is just replacing text in the found file, why don't you open the file and use a regex replace function ? Probably loads faster than parsing the file manually through specific elements.

I have the searching part done, can anyone help with changing the url in the XML file? Code would be helpful. Here is the searching code from ms.com.
