Trying to define a RE

Hello,

I have a java String which is :

"<test>\n\t<test2>XXXX</test2>\n\t<test3>YYYY</test3>\n\t<node-to-find>\n=
\t\t<tt>\n\t\t\t<ttt>vvvv</ttt>\n\t\t</tt>\n\t</node-to-find>\n</test>"

I want to search a RE which begins by <node-to-find> and ends by =
</node-to-find> inside these two strings, you can have any character.=20

How can you define the RE for that purpose ? I have tried =
<node-to-find>.*</node-to-find>
without success !

Any idea ?

Regards.
