Don't touch that mustard. It's Jerry and Bills.
In VS2008 I tried a replace using RegEx so clean out HTML comment tags(in a large xaml file).
Regex:
<!--(.|\s)*?-->

This is the expression I found on a website, I made sure the replace box had that checkbox checked to use regular expressions, yet it found no matches. Did I miss something?

Noting that it's from Swansons Illustrator to Xaml plugin so the comment tags do have "start tags" in them like this quick example:
<-- BLAH BLAH <Path> BLAH -->

If that makes a difference in the RegEx not working.

You need to change the regex a bit:

\<!--(.|\s)#--\>

because:

  • <> have special meaning and they need to be escaped
  • *? is not supported but # does the same thing (lazy *)


PS:
I assume "<-- BLAH... " was a spelling mistake, it's missing a ! so it won't match anyway.

Sweet....that worked, thx.

Now since I have the comments out I need to fing a regex for line breaks...since there's now 2 spaces in between each element in the Xaml Smiley

It's generated by Mike Swansons Illustrator to Xaml and emailing him he says he won't be updating it anytime soon Sad

Someone else needs to take it over....it's a damn handy tool...

One solution is this:

replace \n:b*\n with \n

where :b means space or tab

And speaking of newlines:

The previous regex for comments doesn't handle newlines in comments (and \s is wrong/unneeded), this one does: \<!--(.|\n)@--\>

Sweet.

Now one more Smiley

Since the Illustrator -> Xaml outputs numbers of the points like this:
F1 M 47.460449,93.699219 L 47.806152,93.698242 L 47.807617,93.833984 L 47.460449,93.834961 L 47.460449,93.699219 Z

Can you use Regex to cut down numbers from, say, 47.806152 down to 47.80? Don't care about rounding and stuff like that of course, just the chopping up of the length of all numbers.

We have an .ai of a Caribbean island and I want to export to Xaml as clean as I can. Already got comments, and line breaks out. Chop down the numbers and this Xaml should be an acceptable size.

Try this:

Find what: <{[0-9MC][0-9]*\.[0-9]^2}[0-9]*
Replace with: \1

Of course, I take no responsability if this will replace those digits with a black hole. Proceed with caution Smiley

Worked perfect thx Smiley

Only problem now is with Visual Studio 2005/2008....they seem to just throw up with Xaml files. Eve ones under a meg. Lots of reflection going on I think.

Here is one good link that talks about RegExp in VSTS 2008. It's part of the MSDN blogs, so it is legit source in my mind.
