Regexp question

[yodaa]

Hi all,

I've tried and tried but I only fail and fail. My problem, a regex query on some XML data.

I have some data

File 1

<user>
   <username>abcabc</username>
   <name>Yo Daa</name>
   <email>yo.daa@tektips.com</email>
</user>
<customer>
   <name>David Dave</name>
   <email>david.dave@tektips.com</email>
</customer>

File 2

<user>
   <username>abcabc</username>
   <name>Jake Snake</name>
   <email>jake.snake@tektips.com</email>
</user>
<customer>
   <name>Yo Daa</name>
   <email>yo.daa@tektips.com</email>
</customer>

I wan't to check if these documents contains the name Yo Daa between the <user> </user> tags (File 1 is of interest, not File 2). Have tried several methods with regex with no success. I use JDOM in some of the other procedures in my app, but it is to slow to use in the procedures where I make searches among several XML documents.

I read the files as normal text (FileReader and BufferedReader). I then compile a Pattern and use matches() (Matcher) to find the string combination.

Is there anyone outthere that might have a solution to this problem?

Found a solution

".*?\\<user>.*?(Yo Daa).*?\\</user>.*?"

But now I have a new question. I want to find all documents containing both Yo Daa and Jake Snake.

Using the pattern

".*?(Yo Daa).*?(Jake Snake).*?"

will NOT give me a match, because my statement requires Yo Daa to be listed before Jake Snake which is not the case.
Using the pattern

".*?(Jake Snake).*?(Yo Daa).*?"

will give me a match.

How can I make my pattern flag a match no mather the placement of the text in the document?

Why not use two patterns, combined by the almighty || OR-operator?
