I want to find and replace values like:
<TAG>heading<foo></foo></TAG><foo>juergen</foo>
goal:
<TAG>heading</TAG><foo>juergen</foo>
I want to remove the <foo> Tags between <TAG></TAG>
Here is my attempt:
replaceAll("</?foo\\b[^>]*>", "");

1Use an XML Parser for that problem. Regex is not the right tool for that job.jlordo– jlordo2013-05-27 22:57:01 +00:00Commented May 27, 2013 at 22:57

1Please stop generically whining about things that very often have a perfectly valid use case. Parsing HTML with a regex is sometimes a good idea, sometimes not, stop trying to pass it off as evil by definition.Niels Keurentjes– Niels Keurentjes2013-05-27 23:36:31 +00:00Commented May 27, 2013 at 23:36

String result = searchText.replaceAll("(<f.*><.*o>)(?=<)", "");

The javascript alternative
txt.replace(/(<f.*><.*o>)(?=<)/g,"") doesn't seem to be removing anything: pastebin.com/N2EpQtJ9Isaac
@Mr.Russian it seems to not like this text:
<TAG>keep!<foo>throw</foo>keep!</TAG><foo>keep!</foo>
Mr. Russian
@Isaac - your example is considerably more complex, but try this
searchText.replace(/(<f.*>.*<.*o>)(?=(.*(?=\<\/T.*)(?=\<\/)))/gm, "")Assuming that foo is empty, you can use:
<([^/][^>]*)></\1>
This searches for an opening tag with an adjacent closing tag of the same name.
You could augment it to allow for whitespace in the middle with:
<([^/][^>]*)>\s*</\1>

Thankz for your reply, but it doesnt work. The name is <foo>. and i need only replace this name.
Possible duplicate RegEx match open tags except XHTML self-contained tags
Otherwise, here is the regex, do not even ask me to explain, I barely know myself (this is in javascript, some corrections may need to be made for java):
var txt = "<TAG>a<foo>b</foo>c</TAG>d<foo>e</foo>f<TAG>g<foo>h</foo>i</TAG>j<TAG>k</TAG>";
var res = txt.replace(/(<TAG>.*?)<foo>.*?<\/foo>(.*?<\/TAG>)/gm,"$1$2");
// ( $1 ) ( $2 )
