Crazy Visual Studio regex

I'm not sure why, but I've never really looked into regex in the find (& replace) dialog in Visual Studio. A couple days ago I had an interesting reason to dig in, so here's my attempt to be able to do this the next time I need to.

First here are the docs on the syntax (of course I looked for this after I finished my task, so below may not be the best example): http://msdn.microsoft.com/en-us/library/aa293063(VS.71).aspx

Here are the two expressions I ended up with (I'm sure they could be better):

Find: ^{:b*}proxy\::b*new Ext.data.AspNetAjaxHttpProxy.*\n[^'"]*['"]{[^'"]*}['"]\n[^,]*

1. A line that starts with some white space captured
2. then "proxy:"
3. then some white space
4. then "new Ext.data.AspNetAjaxHttpProxy"
5. then any characters to the end of the line
6. then new line
7. then any characters except a single or double quote
8. then a single or double quote
9. then capture the characters inside of the quotes
10. then a new line
11. then any characters that are not a comma

Replace: \1proxy\: window.getProxy('\2')

1. fill in with the whitespace captured in step 1 above
2. then insert "proxy: window.getProxy(
3. then the chars capterd in step 9 above
4. then insert )

Find: ^{:b*}reader\::b*new Ext.data.JsonReader\(.*\n.*\n[^,]*,:b*
Replace: \1reader\: window.getJSONReader(

Some of the things I learned:

1. There is multi-line support, but it's not great
2. I would have been better off using :q for my quoted string in the first example
3. You can do grouping with "()" to capture n number of \n characters. I didn't know about this at the time, but could have used it where I have back to back ".*\n" sequences.
4. Capture groups are pretty easy using "{}" and replacing with "\n" where 'n' is the 1 based index of the capture.
