Hi Rahamathulla_J,

It can be done either using some string manipulation or potentially complex regular expressions (depending on how complex it needs to be -i.e. do you need to extract a value from a node nested so many levels down  in the document), but is there a reason why you can't load it into an XMLDocument object?

It would save you reinventing the wheel.

Hey!

If you only need to retrieve name of tags then that can be done by reading the xml as a string.
Read that string fowrard by using IndexOf method of string passing "<" as parameter. This would give you index of starting tag read it till indexof(">") (in this way you will get the tag name), then delete the string read so far... keep repeating this in a loop till end of the string.

You can also use a simple regular expression to search for strings of format "<a-zA-Z>". remember this is not the regular expression but the format that u would search for.

here is a regular expression that would match any tag without attribute and starting with a alphabet!

<[A-Za-z][A-Za-z0-9]*>

and this reg exp would match anytag (ofcource without attribute) <[A-Za-z0-9]*>
