How do I split a large xml file?

Question

We export “records” to an xml file; one of our customers has complained that the file is too big for their other system to process. Therefore I need to split up the file,

Answer 1

As mentioned already the xml_split from the Perl package XML::Twig does a great job.

Usage

xml_split < bigFile.xml

#or if compressed e.g.
bzcat bigFile.xml.bz2 | xml_split

Without any arguments xml_split creates a file per top-level child node.

There are parameters to specify the number of elements you want per file (-g) or approximate size (-s <Kb|Mb|Gb>).
