AWK - split XML subnodes into separate files

xml-split.awk

# This awk script splits an XML file and exports X nodes 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 "myNumberOfNodesByOutputFile" by your number of nodes by output file
#    - Replace "myChildNode" by your tag
#    - Replace "myParentNode" by your parent tag
# Run:
#    $ awk -f xml-split.awk myXML.xml

/<myNode>/ {
        rfile="./out/part-" count ".xml"
        print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" > rfile
        print "<myEOF>" > rfile
        print $0 > rfile
        for ( iLoop=0 ; iLoop<myNumberOfNodesByOutputFile ; iLoop++ )
        {
            getline
            while ( ( $0 !~ "<\/myChildNode>" ) && ( $0 !~ "<\/myParentNode>" ) )
            {
                print > rfile
                getline
            }
            if ( $0 !~ "<\/myParentNode>" )
            {
                print $0 > rfile
            }
        }
        print "<\/myParentNode>" > rfile
        close(rfile)
        count++
}

it works great! thanks!
