conversion from one *format in a text file* -> to xml

[Raghavendra Mahuli]

Hello,

I have a text file in which records are stored in a particular format. For
ex:

Node1( att1, att2, node2(attx))

I need to convert it to xml. I know xsl can be used to convert *xml to* some
other format. But i need the reverse operation.
Same thing in xml has to be transformed to something like(need not be
exactly):

<n name="Node1">
<a> att1</a>
<a> att2</a>
<n name="node2">
<a>attx</a>
</n>
</n>



Can u pls give me some pointers to convert a predefined format to xml.


thanks in advance.
warm regards

This looks like the parameters like node2 may be
deeply nested. In this case, you really need a
parser for your own data format. This is not as
trivial as converting simple tables to XML.

You probably need something like lex and yacc in
this case. As an alternative, I have used awk for
implementing such a parser.

Take a look at :
http://www.idealliance.org/proceedings/xml04/papers/111/mhk-paper.html#S2
..
if you have access to XSLT 2.0 (e.g. via Michael Kays saxon 8.x.x) then
you can 'upconvert' plaintext to xml using an xslt. I had a similar
task, but i have to admit I ended up using a lot of "tokenize" followed
by "for-each" structures rather than the "analyze-string" as advocated
in the article. My regex wasn't up to scratch, probably.
