Split file using perl and rename output files based on data in file

Hi there,

I have an input file that is a concatenation of multiple files (variable length).
I am trying to write a perl script that will split the concatenated file into the multiple files that it is made up of.

E.g. the input file is as follows

<start>
customer-id="100"
data 1
<end>
<start>
customer-id="200"
data 2
<end>

The text "<start>" and "<end>" always delimit the files within the input file.

So in this case there would be two new files.

I also need to name the output files with the customer-id that is containned in the data.
So the first output file would be called, for example, 100.out and it would contain
<start>
customer-id="100"
data 1
<end>

and similarly for the second and ay subsequent files

Is all of this possible?

Thanks in advance.
