How to get all the xml tags in perl?

Hi,

I have 2 questions:
a) Does getElementsByTagName in xml takes more time?
b) If it takes more time what are the other alternatives used to get the tag names?

Code:
For example:
<Student>
<Studname>aaa</Studname>
<Studno>123</Studno>
</Student>


This is just a sample data. The file will be very huge in practical applications
loads of tags will be there.

Are there any other methods available in parsers to get all the tag names?


Regards
Vanitha

DOCBOOK2GJOTS(1)					      General Commands Manual						  DOCBOOK2GJOTS(1)

NAME
docbook2gjots - Convert a DOCBOOK file to gjots format (on stdout) SYNOPSIS
docbook2gjots [ DOCBOOK-file ] DESCRIPTION
docbook2gjots converts a DOCBOOK XML file into gjots format. docbook2gjots uses gawk(1) to perform the conversion. <preface>, <chapter>, <section>, <sect1>, <sect2>, <sect3> and <sect4> tags are used to define NewEntry and NewFolder boundaries. They should definitely have <title> tags. This is a quick and dirty hack using gawk(1) and does no formal checking of XML or SGML syntax nor does it validate against the DOCBOOK DTD. Consequently, if the syntax of the file is broken the conversion will probably fail. It is intended that a round-trip can be made so that gjots(1) can be used as a tool at all stages of DOCBOOK production - mainly as an out- line processor to help the author organise and order the work. A document may well start its life in gjots(1) as the initial thoughts are marshalled. As the document forms up, it can be converted to DOCBOOK with the following command which automatically adds tags such as <?xml...>, <para> etc: gjots2docbook -b file.gjots >file.xml docbook2pdf file.xml Or, starting with an existing DOCBOOK file: docbook2gjots file.xml >file.gjots In the latter case, the document will already have a lot of DOCBOOK tags so to convert back to docbook, add the -e and -p options: gjots2docbook -b -p -e file.gjots >file.xml docbook2pdf file.xml AUTHOR
