Splitting XML file into multiple at given tags

Question

I want to split a XML file into multiple files. My workstation is very limited to Eclipse Mars with Xalan 2.7.1.

I can also use Python, but never used it before.

There's an excellent tool http://xmlstar.sourceforge.net/docs.php which can do a lot with xml (however it's not pythonic).

Given you have a 1.xml file with the data as above. And you need to split it to separate files with names NNN.xml with element /root/row.

Just call in shell:

    $ for ((i=1; i<=`xmlstarlet sel -t -v 'count(/root/row)'  1.xml`; i++)); do \
          echo '' > NAME.xml;
          NAME=$(xmlstarlet sel -t -m '/root/row[position()='$i']' -v './NAME' 1.xml); \
          xmlstarlet sel -t -m '/root/row[position()='$i']' -c . -n 1.xml >> $NAME.xml; \
          echo '' >> NAME.xml
       done

Now you have a bunch of xml files like Joe.xml
