Re: EdSharp - Another Regular Expression Question

Hi Jamal --
Well that was simple -- when all else fails, read the instructions...*smile*
And this would be like C comments, matching everything after the <note>, 
including nested <note> elements and terminating when it hits the first 
</note> -- which is probably what was wanted in the first place. Now if he 
wanted to handle nested snotes, or do any other recognition and 
transformation of stuff in the note, that would complicate things..
Thanks for clarifying.

EdSharp fully supports the regular expression syntax of the .NET
Framework, documented at

http://msdn2.microsoft.com/en-us/library/hs600312(vs.80).aspx

A regular expression can match multiple
lines, though the expression is a bit more
complex because the . symbol matches any
character except a new line.  Thus, one has
to match either . or \n in an alternation
group.

I think Jim can do what he wants using the
Extract with Regular Expression command,
Control+Shift+E, with the following
expression:

(?<=<note>)(.|\n)*?(?=</note>)

This gathers non-greedy matches of characters between the <note> and
</note> tags, where the tags, themselves, are excluded from the match
text.  EdSharp puts the results in a new document window.  Each match is
seperated by the section break sequence from the next one.  The section
break characters may be removed with the regular Replace command,
Control+R.
