for-each loop issue in xforms.

Hi All,

By defalut xsl:for-each taking data from main-instance in my xforms.I want to take data from template-instance.

If i write for-each loop like below, it thorws a exception.

<xsl:for-each select="instance('template-instance')//records/record">

<xsl:for-each>

How to write for-each which gets data from template-instance?

Pl help me.

i think you can't access the model using instance() because xslt is
processed before the xforms engine takes over the document. If this is
correct, you still have different options:

- preprocess your template-instance as needed;
- aggregate your instances to a single instance so xslt can access it;
- keep your template-instance and use xforms and repeat to iterate over
the nodeset.

Florian is correct. I would like to add, that you can access variables in XSLT -- you
can define multiple inputs, which are accessed as separated variables --
an alternative to aggregating the instances:

Laxmi,

From XForms, you should instead use xforms:repeat.
