Apex stub from an xml with attributes

Question

I have created apex stub classes from a wsdl and invoked a external SOAP webservice from it. The response is an xml with attribute in elements. I need to extract the value (which is 'PPPPPP' when wd:type="Item_ID" in below xml

<wd:Sales_Item_Reference>
     <wd:ID wd:type="WID">9d89472a929901c34895bc41a6259610</wd:ID>
     <wd:ID wd:type="Item_ID">PPPPPP</wd:ID>
</wd:Sales_Item_Reference>

These are the corresponding stub class methods generated

//for Sales_Item_Reference
public class Sales_ItemObjectType {
        public SOAPStub.Sales_ItemObjectIDType[] ID;
        private transient String[] ID_type_info = new String[]{'ID',s_ns0,'Sales_ItemObjectIDType','0','-1','false'};
        public String Descriptor;
        public String[] Descriptor_att_info = new String[]{'Descriptor'};
        private transient String[] apex_schema_type_info = new String[]{s_ns0,'true','false'};
        private transient String[] field_order_type_info = new String[]{'ID'};
}

//For ID
public class Sales_ItemObjectIDType {
        public String input;
        private transient String[] input_type_info = new String[]{'input','http://www.w3.org/2001/XMLSchema','string','1','1','false'};
        public String type_x;
        public String[] type_x_att_info = new String[]{'type'};
        private transient String[] apex_schema_type_info = new String[]{s_ns0,'true','false'};
        private transient String[] field_order_type_info = new String[]{};
}

Sales_ItemObjectIDType.type_x gives me the attribute value 'Item_ID' but how do I retrieve the value 'PPPPPP'

Answer 1

Based on your example response of:

<wd:Sales_Item_Reference>
     <wd:ID wd:type="WID">9d89472a929901c34895bc41a6259610</wd:ID>
     <wd:ID wd:type="Item_ID">PPPPPP</wd:ID>
</wd:Sales_Item_Reference>

I'd expect to access the Element value of PPPPPP via Sales_ItemObjectIDType.input. This isn't the elements attribute, but rather its value.

Something like this:

Sales_ItemObjectType calloutResponse = // the result from some callout
for(Sales_ItemObjectIDType objectType : calloutResponse.ID) {
    if(objectType.type_x == 'Item_ID') {
        System.debug('Item_ID is ' + objectType.input);
    }
}
