Urgent - xpath problem
|
|
| Kerry Reynolds 2005-02-22, 2:46 am |
| I have an urgent problem with an xpath query running on the following document:
<?xml version="1.0" encoding="utf-8"?>
<ns0:AssetsInOrder xmlns:ns0="http://CompleteOrder.Schema.AssetsInOrder">
<AssetGuid>546B302A-0026-483D-A06E-075684F05221</AssetGuid>
<AssetGuid>9114049E-7D5A-4382-945A-2DE5365D4C87</AssetGuid>
</ns0:AssetsInOrder>
I run it through the following expression shape (to iterate through the
items):
xpathString = System.String.Format("//*[local-name()='AssetGuid'][{0}]",
currentAsset);
outputString = xpath(Message_2, xpathString);
But all I get is a "<AssetGuid xmlns=''> was not expected." when it tries
the xpath() part.
Am I missing a patch or something in the query?
The following is the full error raised
Uncaught exception terminated service
Orchestration.CompleteOrder.MainProcess(4d3aa2f1-d9cc-3732-c5d6-bd63769eac59), instance b7c7cdce-9148-4f7f-8c72-625b4d8efd61
There is an error in the XML document.
Exception type: InvalidOperationException

System.Xml.Serialization.XmlDeserializationEvents)

If you go to your schema, and click on AssetGuid - you will see the complete
and correct Xpath in a property called "Instance Xpath".
/*[local-name()='AssetsInOrder' and
namespace-uri()='http://CompleteOrder.Schema.AssetsInOrder']/*[local-name()='AssetGuid' and namespace-uri()='']
You might also need the "string" parameter as in this example from Biztalk
help:
myString = xpath(msg, "string(/*/book[1]/title)");
So maybe try:
xpathString = System.String.Format("/*[local-name()='AssetsInOrder' and
namespace-uri()='http://CompleteOrder.Schema.AssetsInOrder']/*[local-name()='AssetGuid' and namespace-uri()=''][{0}]",
currentAsset);
outputString = xpath(Message_2, "string(" + xpathString + ")" );
or if you want to use the // the following might work???
xpathString = System.String.Format("//*[local-name()='AssetGuid' and
namespace-uri()=''][{0}]",
currentAsset);
