How to use regular expressions to find a word and copy it to a specific location?

Question

Regular Expressions

Tell me, please, how can I use regular expressions to find what is written between the tags, copy it and paste it between the tags?
I've been racking my brain for an hour, I can't find a formula))

Example:

<category id="1"><name>Мужские куртки</name><short></short></category>
<category id="2"><name>Мужские брюки</name><short></short></category>
<category id="3"><name>Мужские портянки</name><short></short></category>

Need:

<category id="1"><name>Мужские куртки</name><short>Мужские куртки</short></category>
<category id="2"><name>Мужские брюки</name><short>Мужские брюки</short></category>
<category id="3"><name>Мужские портянки</name><short>Мужские портянки</short></category>

Answer 1

Find: (<name>([^<]+)</name>\s*<short>)\s*(</short>)
Replace: $1$2$3
