I have a web bot which extracts some data from a website. The problem is that the html content is sent without line brakes so it's a little bit harder to match certain things so I need to extract everything that is between td tags. Here's a string example: <a class="a" href="javascript:ow(19623507)">**-**-**-***.cstel.net</a> (Used)</td><td><a class="a" href="javascript:ow(19623507)">**-**-**-***.cstel.net</a> (Used)</td> And my regex so far: <a\s+class="a"\s+href="javascript:ow\((.*?)\)">.+</a>(?!<td>).+</td> But my regex matches the whole line instead of matching all contents. Any ideas?

And my regex so far:

<a\s+class="a"\s+href="javascript:ow\((.*?)\)">.+</a>(?!<td>).+</td>

But my regex matches the whole line instead of matching all contents. Any ideas?

Don't waste your time on regexes. Use DOM and XPath.

 DOMDocument::loadHTML($html)->getElementsByTagName('a')

Have you tried changing .+ to .+? ?

Can you determine where the proper line breaks SHOULD be? If so, it might be easier to first replace those tokens with a proper line break and then use the pattern you have (assuming that pattern works - I haven't tried it).

Your pattern looks VERY specific, but perhaps it works fine for what you are doing.
