Regex exclude word

[q1w2e3r4t7]

Hey guys, having some trouble getting a exclude regex function to work.

tried to search as much as i can, and have seen that regex isnt ideal for HTML, however im hoping to get around this by using exclude function.

i want to get the most child html rows, and was hoping to use something like this:

<tr.*(?!<tr).*</tr>

my thinking for this is that it will catch any <tr> ... </tr>, without </tr> in the middle, being the most child row.

However, i cant get it working, can anyone help please.

it can be tested on the following,
<tr> 1 <tr> 2 </tr> 3 </tr>

i would hope to have <tr> 2 </tr> as the result

thanks.

Try this regex

This regex seems to work:

<tr>(([^<]*)|(<(?!tr)))+</tr>

How it works is, it states that between the <tr> and </tr> tags, there can be any number of characters which are not <, and if there is a <, it cannot followed by tr. This inner pattern must be repeated one or more times (which will also match empty tags).

It will need some modification to cope with more elaborate opening <tr> tags.

Good luck
