Renaming xml file based on tag

I have a number of xml files. I need to rename each based on the specific tag (say tag1="alpha") inside the xml. I have figured out how to rename the file based on _single_ occurance of the specific tag.

find . -maxdepth 1 -name '*.xml' -exec /rename.sh {} \;

#!/bin/bash

tag1=$(sed 's/.*tag1="\([^"]*\).*/\1/; q' "$1")
mv -v "$1" "$tag1.xml"

The problem: some files have multiple tag1 tags, e.g. tag1="alpha" tag1="beta" tag1="omega". With these files I need to also create a copies of the same file, but with the other names, beta.xml, omega.xml. I tried to cat with positional parameters but that didn't work (I am a beginner). **file structure example:**
