Split large xml file

Possibly a text editor than can search for the instances of <tele> and </tele>, then save each one off as file1.xml, file2.xml, etc. Then recombine as needed. Prolix seems to be a good choice (for a Windows enviroment). Possibly a Unix/Linux equivalent or run the 16-bit version under Wine...

Can I do it with a shell script? If so, how I will read the file?Since it is xml, my entire file looks to like single line.

XmlMax will do this easily. Just get the free 30 day trial from xponentsoftware

The shell and common Unix tools work on line oriented text data. Since your data is all one large line, you will ultimately over flow the tool's buffer. I am not familiar with XmlMax, but I think you will need something like that. You might search the web for other solutions. If I were solving your problem, I'd create a "C" program that reads in a certain number of characters into a buffer, looks for your terminating characters, and then writes the data with the proper terminating character.

awk '/<tele/{close("row"count".xml");count++}count{f="row"count".xml";print $0 > f}' filename.xml Worked for me

You might want to look at vtd-xml, which is ideally suited for splitting xml http://vtd-xml.sf.net
