Question

I’m trying to get a text within a certain tag. So if I have:

<a href="http://something.com">Found<a/>

I want to be able to retrieve the Found text.

I’m trying to do it using regex. I am able to do it if the <a href="http://something.com> stays the same but it doesn’t.

So far I have this:

Pattern titleFinder = Pattern.compile( ".*[a-zA-Z0-9 ]* ([a-zA-Z0-9 ]*)</a>.*" );

I think the last two parts – the ([a-zA-Z0-9 ]*)</a>.* – are ok but I don’t know what to do for the first part.

Answer 1

As they said, don’t use regex to parse HTML. If you are aware of the shortcomings, you might get away with it, though. Try

Pattern titleFinder = Pattern.compile("<a[^>]*>(.*?)</a>", Pattern.DOTALL | Pattern.CASE_INSENSITIVE);
Matcher regexMatcher = titleFinder.matcher(subjectString);
while (regexMatcher.find()) {
    // matched text: regexMatcher.group(1)
} 

will iterate over all matches in a string.

It won’t handle nested <a> tags and ignores all the attributes inside the tag.
