PHP

Hey!
There is an HTML page containing many tags.

<tag>lolo
ololo
lolo</tag>
<tag>ko
koko
ko</tag>
<tag>zaza
azaza
zaza</tag>
<tag>bom
terebon
bombom</tag>

You need to select only the tag that contains the occurrence of the word azaza:

<tag>zaza
azaza
zaza</tag>

The content of each tag can contain any number of lines.
Problem: jagular #<tag>.*?azaza.*?<\/tag>#shighlights text from the very first tag to the one containing the desired string:

<tag>lolo
ololo
lolo</tag>
<tag>ko
koko
ko</tag>
<tag>zaza
azaza
zaza</tag>
