I have a small perl testing application which glups XML data. All these days I was using XML::Mini Parser, since the XML::Mini has DOM kind of API.

Now I have decided to use SAX based parser (XML::Parser::PerlSAX).
I see in SAX approach the data is collected via call back functions.

This call back thing has made me to re-design stuff, that is call all the rest of the logic from these call back functions, which I don;t want to do.

Instead, I want to read the XML bit by bit and parse it. So I decided to open() the file and read() it.
From the XML::Parser::PerlSAX documentation I found that this module has a method named:

XML::Parser::PerlSAX->location() which returns:

BytePosition The current byte position of the parse.
I am very much intrested in this attribute "BytePosition", I can say, my rest of the logic is depended on this "BytePosition". But unfortunately I din;t find direct method to consume this XML::Parser::PerlSAX->location() function.
The questions I have is:

1. Are there any internel hooks that can return the "BytePosition - The current byte position of the parse."
2. How to lazy evaluate call-back routines of XML::Parser::PerlSAX to fetch limited data on request?

In reply to XML-Parser-PerlSAX how to get the BytePosition value by harsha.reddy
