[SOLVED] Removing duplicate XML markup with awk

Issue

Looking to replace duplicate instances over two lines such as:

<\section>
     <\section>

with a single </section> entry.

Amount of white space in input file may vary.

If this can be done with sed, all the better. But maybe I need to use awk.

Solution

Something like this might work (GNU sed):

sed -Ez 's:(<\\section>)[[:space:]]+\1:</section>:'
