Get posted instance via String xml

This post was updated on .

Hi,

I'm trying to get a parameter sent via post and bind it to an instance. The parameter contains a String with the XML code of that instance. And in the form I do it like this:

<xforms:action ev:event="xforms-ready">
<xforms:insert
context="instance('list_paper')" nodeset="item"
origin="xxforms:get-request-parameter('list_paper')"/>
</xforms:action>

But it doesn't work. Using the inspector the instance becomes with this code:

<root xmlns:xbl="http://www.w3.org/ns/xbl" xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:saxon="http://saxon.sf.net/"
xmlns:xxi="http://orbeon.org/oxf/xml/xinclude"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:fr="http://orbeon.org/oxf/xml/form-runner"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:sql="http://orbeon.org/oxf/xml/sql"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xpl="java:org.orbeon.oxf.pipeline.api.FunctionLibrary"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:exforms="http://www.exforms.org/exf/1-0"
xmlns:fb="http://orbeon.org/oxf/xml/form-builder">
<item>
<label>titular1</label>
<value>0</value>
</item>
<item>
<label>titular2</label>
<value>1</value>
</item>
<item>
<label>titular3</label>
<value>2</value>
</item>& lt;root& gt;
& lt;item& gt;
& lt;label& gt;titular100& lt;/label& gt;
& lt;value& gt;0& lt;/value& gt;
& lt;/item& gt;
& lt;item& gt;
& lt;label& gt;titular200& lt;/label& gt;
& lt;value& gt;1& lt;/value& gt;
& lt;/item& gt;
& lt;item& gt;
& lt;label& gt;titular300& lt;/label& gt;
& lt;value& gt;2& lt;/value& gt;
& lt;/item& gt;
& lt;/root& gt;
</root>

(without the spaces between the gt and lt and the &)

It is the default instance hard coded in the form plus the content that comes from parameter. But why is it not binding well?

Administrator

xxforms:get-request-parameter returns a string, and that's what gets
inserted into the instance

What you want is to parse the string before inserting. Try:

<xforms:insert
context="instance('list_paper')" nodeset="item"
origin="saxon:parse(xxforms:get-request-parameter('list_paper'))"/>

And make sure you have xmlns:saxon="http://saxon.sf.net/" declared.

Re: Get posted instance via String xml

Hi,

Thank you very much for the solution! There is another solution though, is passing attribute xml via Document instead of String and using this code in the form:

<xforms:action ev:event="xforms-model-construct-done">
<xforms:insert
nodeset="instance('list_paper')"
origin="xxforms:get-request-attribute('list_paper')"/>
</xforms:action>

Thanks,
Henrique Barros
