Looks like my understanding of negative lookaheads is lacking.

I have this test string:

Open in new window

and the following expression:

Open in new window

I want to match "text" followed by "code" in the same row.
That is, "code" should follow "text" before "<\tr>".
In the sample, the only match should be

Open in new window

How can I write the regular expression for that?

I believe this is what you are after:


Open in new window

Basically, you simply look ahead of the current character matched by the dot, and you check to make sure that the following text is not the closing row tag. There may be a more elegant way to do it, but this should suffice for your current need.
