retrieve quoted string using expression language

Question

How to retrieve the quoted value of a property.

suppose you have some expression like:

[html:text property="pqrs" styleClass="text" style="width:200px"].

And now i want to retrieve the value of property, styleclass and style ie "pqrs", "text" and "width:200px" respectively.

Can you guys please help me in this.

thanks a lot.

If you just want the text in quotes, a non-greedy match should work:

".*?"

can you please write the matcher method that will return the quoted string using your expression. Thanks a lot

@Kuri - sorry, I've never written a non-trivial java program. If you need more detail, hopefully someone will come here and answer your question. I came here via the [regex] tag.

(\w+)\=\"(.*?)\"

The first capture group (\w+) gives you the attribute name, and the second capture group uses a non-aggressive operator to match things inside quotes.

Thanks i got the answer, your expression works. Implementation using java code: String property =(string)="\"(.*?)\""; Pattern startingPattern = Pattern.compile(property); if(match.find()){ System.out.println("found"); for(int j=0; j<match.groupCount(); j++){ System.out.println(match.group(j)); }

Sorry, my Java is also a bit rusty. But you sure should know how to create a regex and execute it, otherwise you probably shouldn't be using regex's in the first place.
