I have a rather large (1.3 GB) KML file that I need to split into smaller more manageable files (that SimpleXML won't choke on). I have not been able to find a good script to do that, and I am not too familiar w/ XML in PHP. Has anybody had luck splitting up a large XML file into to smaller, well-formed XML files?

1.3 Gb...
Wow, that's a big Dom document...

I'm curious, but sorry to say I don't know of anything...
What about the structure though ?
Is it always the same pattern repeating over and over ?

If so, you should be able by parsing the document line by line to detect each primary entity beginning and end, and spit them out in smaller files.

That would work considering it is a well formed XML document but I wanted to see if anybody had a solution before I went knee deep in code

I think Tripy's approach will be the simplest to implement.

I ended up modifying a script I found on google (How-to Handle Large XML Files in PHP) to make it work. It basically follows the approach Tripy suggested. I ended up with 2500+ files, that were plenty small for SimpleXML to handle. Thanks for your help.

Note: The script I linked does NOT work out of the box, it takes some tweaking.

I did come across this...

Never used it before though, so couldn't say if it's any good. But it does split large files, and it also puts them back together again. Sounds a lot similar to WinRaR.

Unfortunately that would not have worked in this situation, because I needed to split it into well-formed XML documents that could be read using an XML parser.
