Question

I have XML like

<A>
 <B>
  <C>
   Hello World
  </C>
 </B>
</A>

I want to replace the starting tag’s "<" with "<ns:" in each tag resulting the following XML

<ns:A>
 <ns:B>
  <ns:C>
   Hello World
  </ns:C>
 </ns:B>
</ns:A>

What should be the regular expression I should use in text editor to replace and include the namesapace

I was trying to use regex [<][^/] but it selects the 1st character of the starting tag also which I don’t want to replace.

Note: I have the above requirement for manual editing purpose in an editor where regex replace is supported. I was not going to do the above task programmatically .And the output XML fragment requested is an inner part of the complete XML , hence namespace URI is not mentioned

Answer 1

Use this regex replacement:

regex: (</?)
replacement: $1ns:
