AWK - split XML subnodes into separate files

split-xml.awk

# This awk script splits an XML file and exports each node into separate file
# It doesn't work if the main node has an attribute
# It doesn't work if the main node contains a subnode with the same tagname, etc.
# Use at your own risk, think before using.
# Usage - replace "node" by your tag and run: $ awk -f split-xml.awk my.xml
/<node>/ {
        rfile="node" count ".xml"
        print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" > rfile
        print $0 > rfile
        getline
        while ($0 !~ "<\/node>" ) {
                print > rfile
                getline
        }
        print $0 > rfile
        close(rfile)
        count++
}
