Accessing instance data in XPL

I am having trouble getting the text value of the input document to be included in the select portion of my copy-of statement. Everything I try results in a XML file output of <path>/a/b/c</path>, but what I need is a subset of the file.xml beginning with the path /a/b/c. Any help is appreciated.

Input document XML that is instance for XPL

<submission>
<path>/a/b/c</path>
</submission>

XPL

<p:param name="instance" type="input">

<p:processor name="oxf:xslt-2.0">
<p:input name="config">
<xsl:stylesheet version="2.0" xmlns:xsl="http://www....">

<xsl:template match="/">
<xsl:copy-of select="NEED INSTANCE INFORMATION EVALUATING TO /a/b/c"/>
</xsl:template>
</xsl:stylesheet>
</p:input>
<p:input name="data" href="oxf:file.xml"/>
<p:output name="data" id="subset"/>
</p:processor>

Re: Accessing instance data in XPL

I believe what you want is a User-Defined input

<xsl:copy-of select="instance('my-inst')/a/b/c"/>

.....

<p:input name="my-inst" type="input"/>

Cheers,
Hank

Re: Re: Accessing instance data in XPL

In reply to this post by stacyladnier

This isn't a copy-of select within an XFORM. All of this is within an
XPL file.

The Xform submitted an instance that is the XML listed below. From
within the xslt processor, I need to access that instance so I can
dynamically insert the string value of /a/b/c into the select attribute
of the copy-of tag.

I need the contents of the copy-of to be
<xsl:copy-of select="/a/b/c"/>

where /a/b/c is the text contained in the instance/submission/path element.

Using instance throws an error indicating instance() is an unknown
system function.

RE: Re: Re: Accessing instance data in XPL

It sounds like you need two xslt processors in your xslt.

Your first processor will build an xslt for input into the second processor.
Ie it will get the contents of /submission/path, and use that to build the
"xsl:copy-of" statement within an xslt which will be the input to the second
processor.

I'm assuming that what you want is:

Your instance input:

<submission>
<path>/a/b/c</path>
</submission>

First xslt output:

...
<xsl:copy-of select="/a/b/c"/>
...

Then your 2nd xslt will use this as the stylesheet input, and it will use
your "data" pipeline input as the data input.

You will have to mess around a bit with namespaces to get the first one
working properly - take a look at xsl:namespace-alias - there's an example
here - http://lenzconsulting.com/namespaces-in-xslt/#namespace-alias

You probably want something like this in your first xslt processor (I
haven't tested this!):

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:out="http://www.example.org/dummy">


<xsl:namespace-alias stylesheet-prefix="out" result-prefix="xsl"/>

<xsl:template match="/">
<out:stylesheet version="1.0">
<out:template match="/">
<out:copy-of>
<xsl:attribute name="select">
<xsl:value-of select="/submission/path"/>
</xsl:attribute>
</out:copy-of>
</out:template>
</out:stylesheet>
</xsl:template>

</xsl:stylesheet>

Then your 2nd xslt processor will use this as the "config".

Oops! I meant:

It sounds like you need two xslt processors in your xpl.
