Matching substrings within a Regex

the pattern 4 this would be

AccountNumber="(\d)\d*".*?StreetNumber=&qu
ot;\1\d*"

w/SingleLine Option ON

be aware that it 'll match on broken strings like : (it's
a whole
match)

AccountNumber="11324324" blablablablabla
AccountNumber="345635" blabla
StreetNumber="6789689"
StreetNumber="11322345"

i.e when by mistake one Acc#-Street# pair is nested inside
another.

if u had shown what kind of text that *blahblah* is , we
could try and
write a more robust regex 4 this.

Thanks for the response.
I am only using this expression for manually searching for
irregularities in a log file, so it doesn't have to bee too
robust;
it's a one time deal.
I didn't know about backreferences, and that was what was
holding me
back.

Sergei, perhaps you could help me with another problem I'm
having.
I'm using a tool called Windows Grep 2.3, and I can't seem
to get it to
recognize certain expressions.

Example:
I cannot get GREP to recognize the following expression:
     \d

Although it will recognize:
   [0-9][0-9][0-9][0-9]

I am having the same problem with the search utility in
Visual Studio
dot net.
Do these tools require some special syntax that I am not
aware of?

Thanks,
Jonathan

i'm 99% sure that any regex tool should recognize such a
basic pattern
as

\d

let alone VStudio where I work myself. Can u show more
details on what
u r doing?

The following instructions refer to VS2003, but the VS2005
editor is
very similar:

1) Open up visual studio and create a new text file.
    A new file should be visible in the editor.

2)  Into the file, enter this string:

     sdfgsfdg1234sdfgsf

3)  In the IDE menu, select Edit --> Find and Replace
--> Find.
Check the checkbox that says "Use regular
expressions" and type in the
following search string:

     \d

The string won't be found.

The following search string works however:

     [0-9][0-9][0-9][0-9]

I don't know if this is a limitation of the tool, but
Windows GREP
behaves the same way!

Thanks,
Jonathan

u seem to be using a (very) light-weight Find/Replace applet
in
VStidio, much like MS Word Fid/Replace with some (very
little ) regex
support (MSoft even have decency not to call it regex but
rather
'wildcards' inside the app). This kind of toll will not
indeed offer u
even such basic syntax as \d or \w.

The Q now is why would u want to use this limited tool,
having all
tremendously versatile  regex power of MS VStudio within
your reach?
