You are right ..the web service returns XML and the binding expression has no idea what the structure is. I created soemthing similar for another project and I will paste the script below. You will jave to modify it but you will get the idea.
You will have to create a field on the form (make it hidden when you are finished) that will hold the result of the web service call. Don't forget to make it multi-line. Once the web service executes and the XML is in the field you need to load the XML into the Dom then manipulate the Dom to get the nodes that you want. In my case you enter a search criteria to find users and when you hit the button the web service executes and the results are returned in an XML structure. I then populate the dropdown so you can pick who to route the document to. Here is the code:
//Clear Dropdown lists
DropDownList2.clearItems();
DropDownList2.rawValue
= "";
//check to see if the user put a value in the search filter
if
(lookup_string.rawValue == null) {
//Ooops no value
app.alert('You must enter a search criteria...');
}
else {
//Got a value now lets invoke the WS
invokeBtn.execEvent('click');
//Load the returned XML in the Dom at the same level data. The false, false are flags that say to overwrite if the node exists and to keep child nodes
//xml_result is the name of my temp field
xfa.datasets.data.loadXML(xml_result.rawValue
, false, false);
//This is a debug step. I will write the Dom to the field so I can see the structure
xml_result.rawValue
= xfa.datasets.data.saveXML("pretty");
//Find the nodes that I want and assign them to theDataGroup - subset of the entire Dom
var theDataGroup = xfa.resolveNode("xfa.data.people");
//get the length of the subset Group
var len = theDataGroup.nodes.length;
//cycle through each node and add the name of the person to the dropdown. Each User node has a Name node and then other info. The Name
//node is always 1st so I know that it is occuraance 0
for (var i=0; i < len; i++){
DropDownList2.addItem(theDataGroup.nodes.item(i).nodes.item(0).value);
}
}
//Clear the temp field
xml_result.rawValue
= "";
//Remove the added nodes
var
oRemoveNode = xfa.resolveNode("xfa.data.people");
The structure of the XML is like this:
<people>
<person>
<Name>
<Email>
<Address>
</person>
<person>
.....
</people>
You must be familiar with the XML as well as pretty good with code if you want to undertake this.
Hope that helps
