capture group - regex

[stefanwagner]

Well, I searched here without success, and don't get it by reading the java-docs.

I want to split a certain token like this:
<name>groovy</name>
to
<name>
groovy
</name>
(xml-tag, content, xml-tag)

I use string.replaceAll (pattern, matcher) like this:
(the typical hardly readable regex-syntax)

tmp = tmp.replaceAll ("<([^>]+)>([^<]+)<([^>]+)>", "<\\1>\n\\2\n<\\3>");

the result isn't - as intended - but:

<1>
2
<3>

The pattern is found, but the backreferences aren't interpreted the way I like.
How would I specify the capturing-group 1, 2, 3 correctly?

Found it myself (in JDC Tech Tips):

tmp = tmp.replaceAll ("<([^>]+)>([^<]+)<([^>]+)>", "<$1>\n$2\n<$3>");

Even after knowing this, I don't find it in the Javadocs...
