xxf:get-request-attribute()

xxf:get-request-attribute(
    $name         as xs:string,
    $content-type as xs:string?
) as item()?

The xxf:get-request-attribute() function returns the value of the given request attribute. The attribute may have been previously placed in the request through Java code, or using xxf:set-request-attribute(), for example.

The types of attribute objects supported are the same [types supported by the Scope generator][3], plus types stored with xxf:set-request-attribute().

If present, the second parameter can specify the text/plain content type. In that case, if a String object is retrieved, it is return as an xs:string instead of being parsed as XML.

<!-- Get the "document" attribute and use it to replace instance "my-instance" -->
<xf:insert
  ref="instance('my-instance')"
  origin="xxf:get-request-attribute('document')"/>

NOTE: This function can only be called during page initialization, otherwise it will throw an error. We recommend you use it only within event handlers called as a result of processing xforms-model-construct-done or xforms-ready, or from the xxf:default MIP.
