Regular expression with multiple results

What's wrong with my regex ?

"/Blabla\(2\)&nbsp;:.*<tr><td class=\"generic\">(.*)<\/td>.+<\/tr>/Uis"

....

<tr>
<td class="aaa">Blabla(1)&nbsp;:</td>
<td>
<table class="bbb"><tbody>
<tr class="ccc"><th>title1</th><th>title2</th><th>title3</th></tr>
<tr><td class="generic">word1</td><td class="generic">word2 </td><td class="generic">word3</td></tr>
<tr><td class="generic">word4</td><td class="generic">word5 </td><td class="generic">word6</td></tr>
</tbody></table>
</td>
</tr>

<tr>
<td class="aaa">Blabla(2)&nbsp;:</td>
<td>
<table class="bbb"><tbody>
<tr class="ccc"><th>title1</th><th>title2</th><th>title3</th></tr>
<tr><td class="generic">word1b</td><td class="generic">word2b </td><td class="generic">word3b</td></tr>
<tr><td class="generic">word4b</td><td class="generic">word5b </td><td class="generic">word6b</td></tr>
</tbody></table>
</td>
</tr

What I want to do is to get the content of the FIRST TD of each TR from the block beginning with Blabla(2).

So the expected answer is word1b AND word4b But only the first is returned...

Thank you for your help. Please don't answer me to use a DOM navigator, it's not possible in my case.

Thanks to @Jerry, I learn today new tricks:

(Blabla\(2\)&nbsp;:.*?|\G)<tr><td class=\"generic\">\K([^<]+).+?<\/tr>\r\n

That's an interesting regex, in which I learned about the ungreedy flag, nice!

And for your problem, you might make use of \G to match immediately after the previous match and the flag g, assuming PCRE engine:

/(?:Blabla\(2\)&nbsp;:|(?<!^)\G).*<tr><td class=\"generic\">(.*)<\/td>.+<\/tr>/Uisg

Or a little shorter with different delimiters:

'~(?:Blabla\(2\)&nbsp;:|(?<!^)\G).*<tr><td class="generic">(.*)</td>.+</tr>~Uisg'
