search for one value within so many characters of another value - within my source code

Posted on 2013-01-30

In my Visual Studio 2010 Pro dev environment, I want to search for the following two phrases (excluding the quotes, mind you):

"href="

and

"Eval("

once the search engine locates the "href=" I want it to begin searching after this phrase up to say, 50 characters, for the phrase "Eval(".

Is this only to be accomplished through a RegEx type search?


What would be the syntax?  Don't know RegEx very well.

Can you explain a bit more on what you are trying to accomplish? i.e. why a regex to search in VS?

It was so I could find examples like THIS in my source code:

  <a id="linkViewDocument" runat="server" href='<%# "~/ViewDoc.Aspx?DocID=" + Eval("BidDocID") + "-" + Eval("BidDocSID") %>'>View Document</a>

Open in new window

               


You might recognize this from another question of mine you just answered.  : )


I would still like to know how to find snippets like this, which have an href and then later on have an EVAL...

Try something like this:
href=.{0,50}Eval\(.*

Open in new window

FYI: Try tool like Expresso for creating/testing regexs..

Okay.


I'll have to back-burner this for a few hours.

But I will return and give more feedback.

I am sure your RegEx is fine or can be made fine...so the points are yours.  I won't make you wait for me.

Follow-up:

href=.{0,50}Eval\(.*


Did not seem to work.

Well, I take it back.

I downloaded and installed Expresso, and your original Reg Ex worked fine:


expresso test

For some reason it will not work in VS search using RegEx.

Hmmm interesting... I did try it in VS before posting it and it did search the href Eval string that you had in the other post.
Can you post the string you have in your source...
Also make sure you have Regex selected while searching

svs

Notice above in the screenshot I have "Use Regular Expressions" selected via the GUI.



Register.{0,50}Tag.*

should find this line, correct?  (see below)


<%@ Register TagPrefix="uc2" TagName="BigLabel" Src="~/Controls/BigLabel.ascx" %>

I tested in VS2012...and Register.{0,50}Tag.* works as well.
Not sure may be it's the VS version..Let me see
vs regex search
I think it's the issue with the VS you are using. It has is some of the other interpretations. http://www.codinghorror.com/blog/2006/07/the-visual-studio-ide-and-regular-expressions.html

It is not liking the {0,50}

This will work: .*Register.*Tag.*
