c# regexp pattern to ....

Question

I wrote the following pattern:

@"<([0-9]+)>(.*?) < /$1>"

but it doesn't work. how could i refer to the first group?

source text:

"Method()<0>int x = 0; while(x < 10)<1>echo(x)< /1>< /0>"

So, what you are looking for is the first number inside the angle brackets? And then you are also capturing the rest of the string? It would help if in your question you also included the exact text from your souce that you wish to capture. — saunderl, Sep 16 '10 at 16:37
please refer to the following: http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 ... it's not xml, but it's similar. The guy makes a valid point — DaveDev, Sep 16 '10 at 16:39

That would be \1, and watch for spaces.

I don't think `0` is a legal tag name for XML, so an XML parser will probably complain. – strager Sep 16 '10 at 16:34

Even if regex works in this case, do read up on why true regex in general fails to parse XML files. – Hamish Grubijan Sep 16 '10 at 16:36
@strager - Good point, I didn't see these until I edited the question `:P` – Kobi Sep 16 '10 at 16:36

@strager it isn't a tag name it's a value in the node – msarchet Sep 16 '10 at 16:37
@Hamish Grubijan, I'm well aware of this. @msarchet, Pardon? I'm not sure what you're saying. – strager Sep 16 '10 at 16:38
