BASH SHELL SCRIPT to split a big xml file into multiple small files

Not pure answer but you can tune this yourself:

csplit -ksf part. src.xml /\<child\>/ "{100}" 2>/dev/null

This command will split src.xml using regexp /\<child\>/ as a delimiter and produce 1..100 part.* files.You need to play with regexp though...

xml file shell split

One solution is to write a XSL file and use xsltproc with the stylesheet and the xml file to generate the single files.
