Hi guys,

 I'm quite new to the whole RexExp thing (about ~1 hour).

 What I'm trying to do is parse a list of URLs I have. They look like this:

www.domain.com/page.php?Page=123&Article=123

But sometimes, the Article-Parameter is missing. They then just look like this:

www.domain.com/page.php?Page=123

I want to find those with the missing Article parameter. What I tried was:

Page.*(Article){0}

Meaning: I want to find the URL where Page is followed by anything but not "Article". This doesn't work. Do you have any ideas how to do it?

Thanks a lot,

pHew

the solution heavily depends on how exactly you trying to match your strings, in other words, real examples in real text are needed. Leaving alone language/platform you are using, which u also did not mention. Being a programmer, u know that every solution implementation is platform/language specific, regex is no exception. Shooting in the dark, i can offer this sysntax

\bwww\.\S*?Page((?!Article)\S)+(?=\s|$)

assuming that your urls are matched as separate strings delimited either by a white space or a new line

Hello Sergei,

 Thanks for your help. The URLs are not in a file or anything. I use the application A1 Sitemap Generator to generate a sitemap. And it has an option to "Disallow internal links that match regex". So I have no clue what language that is in. It's on Windows Vista, if that helps (I doubt it).

I was thinking I don't need to concern about \b and $, since it just tries to find the regex in the specifig URL. If it is found, the URL is deleted. If not, happy times! The URL is saved.

Unfortunately I don't understand the expression you suggested, besides having read regex tutorials all day long. But I will try to make it! Thanks for your help.

did you try to use the regex? It sh not match on those urls that have a str "Article" in them. U can also drop \b and (?=\s|$).

U can parse the regex in regexBuddy or Expresso to get the meaning of the syntax. Expresso is a free regex tool.

I'm trying right now. Thanks for the tips.

It didn't work :-(

Try this:

^(?!.*?&Article).*$

Matches:

Everything between beginning of line and end of line that does not have &Article located within it.

Note that if the regex is being applied to a complete list at once, you will need to have the singleLine (or dot matches all) option Off.
