Re: EdSharp - Another Regular Expression Question

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.
