How to trim spaces in xml tags using regular expression in notepad++?

Question

I am trying to trim a space in an XML tag, this is an example of what I have:

<xmlT ag>
content between tag
</xmlTa g>

to:

<xmlTag>
content between tag
</xmlTag>

This is the expression that I wrote for that:

Find: [<](\\w)* (\\w)*[>]|[<][/](\\w)* (\\w)*[>]
Replace: \\1\\2

but is not working as expected.
Is there any other workaround for this?

Answer 1

If the tags only have one space in them and no attributes, this will work

find: <(/?)(\\w*) (\\w*)>

replace: <\\1\\2\\3>

Answer 2

Using a LookAhead we can repair any number of spaces in a tag:

Search for: \\s+(?=[\\s\\w]*>)
Replace with nothing

Note: LookAhead is available in NotePad++ since version 6.0
