{IT} is the start of the file.
I have to split the files into many based on {IT} tag and filename with {TAG} value.
and all the contents are written in the file. file should be like for example: 0412270403.xml 
<?xml version="1.0" encoding="UTF-8"?>
<ROOT>
<IT>R</IT>
<DATE>050102</DATE>
<TDATE>Sunday, January 02, 2005</TDATE>

      It is a large file, I have split the files into smaller modules.
      {IT} is the start of one file and filename should be the {TAG} value.
      I am not able to split the files. How can I do it
      Please help me.

        Hire someone :/
[reply]
      please tell me how to split the file into smaller pieces and file name should be {TAG}.
      All the contents should be in a file until it finds another {IT} tag.
      . Right now the script works only if {TAG} is at the firstline as the start of each file. If replace <IT> instead of <TAG>(.*), if the value is same file will be overwritten.
      . Please tell me how can I split the large file into smaller bits.

        What is the name of this format?
