Re: [Xsltforms-support] XForms, data in a repeat from a parallel instance nodeset

[Jason K. <ja...@bi...>]

Good to know about the axes support.  What I've done instead is to make a
new attribute for each node in my answers model, @index, and bind it to
position. Then, I can reference that value with current()/@index from with
the xpath to the question's index.  One downside, potentially is the
addition of the @index.

How are we to reference xf:variables from within xpath or otherwise?  I have
been unsuccessful.  The xsltforms parser doesn't like the '$'.  Can you give
examples?

Thanks,

Jason

Jason,

Axes such as "preceding-sibling::" are not yet supported by the XPath
analyzer of XSLTForms, which is written with XSLT 1.0.

About variables, you can create a work instance for them and use
"xf:setvalue" to change their values.

Thank you for testing XSLTForms!

I'm still stuck on this.  I've tried:

<xf:output ref="instance('questions')/question[position() =
(count(current()/preceding-sibling::*) + 1)]/@text"></xf:output>

but xsltforms keeps complaining about the preceding-sibling::*

Since I need instance('questions')/question[position() =
(count(current()/preceding-sibling::*) + 1)] for several things, I'd like to
be able to store this in a variable and use it throughout my repeater -
however, I'm not sure how xsltforms supports this.

Thanks,

Jason
