iwov_xslt loses opening html tag

Hi.

I have developing some templates which transform DCR's using XSLT.
The TPL's utilise the iwov_xslt tag.

The issue I have is that the opening html tag is missing from the resulting output - therefore the output is not valid x(h)tml.
Has anyone every witnessed this behaviour and if so, did you find a solution?

Thanks.
Darren.

To reply to my own question.....

iwov_xslt.pm line 400

$xslt_data =~ s/[^\n]*\n//;

I simply commented this line out.

$xslt_data =~ s/[^\n]*\n//;

That's a very strange line of code - with no comment to explain what it's supposed to be doing.
I'm guessing it's being used to eliminate the first (or last?) line of data that was captured in that variable - perhaps removing an <?xml...?> header? -
It would be interesting to add some debugging before/after that line to spit out the contents of $xslt_data and figure out exactly what it's doing.

Unfortunately I finished this contract on Friday otherwise I would have spent some time logging the contents of the $xslt_data variable.

I'm suprised nobody has come across this before me. Obviously using XSLT as part of the presentation tier in TeamSite isn't as popular as I thought....

You can, of course just call Xalan transform directly using the perl system function or backticks, and cut the iwov_xslt tag out of your tpl altogether- Doesn't even have to be Xalan, you could install whatever you want.

There is also a module available from cpan (XML::XSLT) which I believe is 100% perl, though I haven't got around to trying this yet.

mmm, just to comment. (we're migrating from ts 55 to ts 65 soon)

I was digging in our code today because of the issue (double UTF-8 encoding by iwov_xslt in TS65) discussed at http://devnet.interwoven.com/forums/cgi-bin/showflat.pl?Cat=&Board=PRODUCTS_TEMPLATING&Number=53382&page=&view=&sb=&o=&vc=1

2 facts I noticed: iwov_xslt.pm has not changed from TS 5.5.2 to TS 6.5 it seems. So that "kill the first line" was also in the TS 5.5. code. The 1st version of our current project has been coded by outside developers. I've noticed just now that they bypassed this issue by putting a "dummy first line" in the .xsl file.

Oh my **** :-(

I have this issue, and it took a little bit of time to identify. I'm glad I came across this thread.

Basically, that code, as fish suggests, is to strip out the line. If you are more than a newbie at XSLT, you might have had this line in your XSL:

which causes the XSL processor to remove the xml declaration for you. So, with IW, you must always have omit-xml-declaration="no", which is the default.

For clarity - without the swallowing of the XML code
