Re: [Exist-open] Adding processing instruction using (X)update with eXist 1.1.1

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi,

another try=20

1) Execute following query in client

let $c :=3D <xupdate:modifications version=3D"1.0"
xmlns:xupdate=3D"http://www.xmldb.org/xupdate">
              <xupdate:insert-before select=3D"/addresses">
                 <xupdate:processing-instruction
name=3D"cocoon-process">type=3D"xsp"</xupdate:processing-instruction>
              </xupdate:insert-before>
          </xupdate:modifications>
return $c

Replace "preceding" with "into" and the pi is inserted as the last child
of the document node.

3)  Following is a listing of the xupdate=20

<xupdate:modifications version=3D"1.0"
xmlns:xupdate=3D"http://www.xmldb.org/xupdate" >
  <xupdate:insert-before select=3D"/document-node()">
    <xupdate:processing-instruction
name=3D"xml-stylesheet">type=3D"text/xml"
href=3D"http://hiexmldb:8080/schema/HostInfo.xsl"</xupdate:processing-inst
ruction>
  </xupdate:insert-before>
</xupdate:modifications>

Executing the XUpdate using the SOAP interface, I get a SOAP FAULT with
faultstring of java.lang.NullPointerException.

There appears to be no stack trace in the log file. Following is all the
apparent output from the XUpdate operation:
