Referring to instance data in a stylesheet

Hi,

I have a xhtml page in which I am also declaring xsl:version="2.0" at
the top since I need to dynamically generate stuff based on the output
of a pipeline. However, there are static elements that I am defining in
an xforms:instance at the top of the page and I was wondering how I can
access these in an xsl statement lower down:

<html xsl:version="2.0">
<head>
<xforms:models>
<xforms:instance id="types">
<type>...
<type>...
...
</xforms:instance>
...
</xforms:model>
</head>
<body>
...
<xsl:for-each select="instance('types')">
...
</xsl:for-each>
</body>
</html>

Cheers,

Matthew

Mathew,

You would reference the instance as follows:

<xsl:for-each select="doc('input:instance')">

Matthew,
To access the instance from XSLT just treat it as the root, so if
you have the following

<xforms:instance id="type">
<instance>
<type>..</type>
<type>..</type>
<type>..</type>
</instance>
</xforms:instance>

The xsl would be

<xsl:for-each select="/instance/type">
...
</xsl:for-each>

Hope this helps

Re: Referring to instance data in a stylesheet

Hi,

This is not the behaviour I see: the page flow part for this xhtml page is:

<page id="publish" view="publish.xhtml" model="publish.xpl"/>

and the xsl elements in publish.xhtml act on the data from the model -
publish.xpl - and not the instance definitions in the xforms:model at
the top of publish.xhtml. BTW I am using OPS 3.0final.

Cheers,

Matthew

RE: Referring to instance data in a stylesheet

Try doc('input:type')/instance/type I don't have eclipse running so I can't
try it

Should work though

Matthew,

So you are saying that the content of your <instance> document is
static, i.e. its values do not come from the model?

Whatever the situation, you can works around this by using variables in
XSLT, e.g.:

<xsl:variable name="my-instance" as="element()">
<instance>
<type>..</type>
</instance>
<xsl:variable>

To copy the whole instance:

<xsl:copy-of select="$my-instance"/>

To iterate over the values:

<xsl:for-each select="$my-instance/type">
...
</xsl:for-each>

You have to be aware that the page view runs only once when the page is
requested, and that your XSLT instructions will not run again when the
user interacts with the XForms page. Also, obviously, XSLT cannot access
any XForms function. You really have to look at this as follows:

o page is requested
o page model runs
o page view runs, including XSLT code
o result of page view is sent to XForms engine
o user interacts with resulting XForms page
