Splitting huge XML Files into fixsized wellformed parts
Hi,

I need to split xml-files with sizes greater than 2 gb into smaler chunks. As I dont want to end up with billions of files, I want those splitted files to have configurable sizes like 250 MB. Each file should be well formed having an exact copy of the header (and footer as the closing of the header) from the original file. Forthermore, a table should be generated were I can see, that the File X is seperated into Part N with timestamp:

The Original XML-Files look like this:

<?xml ...>
<Headerelement with some infos to be copied 1to1>
<OfferInfo>
<OfferID></OfferID>
...
</OfferInfo>
<OfferInfo>
<OfferID></OfferID>
...
</OfferInfo>
<OfferInfo>
<OfferID></OfferID>
...
</OfferInfo>
</Headerelement>

-------------------------
Protocol Table:

Orginalfilename|Name of PartN|Size of PartN|Timestamp

-------------------------

All in all I ended up with reading the XML processing docus of gawk,
but as it seems I am lacking some deeper programming skills.. Could
someone please help?

Thx
Malapha

       -O, --original-string=value
	      XML is contained in the supplied string

   Operation:
