read XML from WebService

Hi, I have the next xml that return my webservice

 

<?xml version="1.0" encoding="utf-8" ?>
- <DataSetGeneral xmlns="...">
- <xs:schema targetNamespace="..." xmlns:mstns="..." xmlns="..." xmlns:xs="..." xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" attributeFormDefault="qualified" elementFormDefault="qualified">
- <xs:element msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
- <xs:complexType>
- <xs:choice minOccurs="0" maxOccurs="unbounded">
- <xs:element>
- <xs:complexType>
- <xs:sequence>
  <xs:element minOccurs="0" />
  </xs:sequence>
  </xs:complexType>
  </xs:element>
- <xs:element>
- <xs:complexType>
- <xs:sequence>
  <xs:element minOccurs="0" />
  </xs:sequence>
  </xs:complexType>
  </xs:element>
  </xs:choice>
  </xs:complexType>
  </xs:element>
  </xs:schema>
- <diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
- <DataSetGeneral xmlns="http://tempuri.org/DataSetGeneral.xsd">
- <CONTENIDO diffgr:id="CONTENIDO1" msdata:rowOrder="0">
  <NOMBRE>A_USER1</NOMBRE>
  </CONTENIDO>
- <CONTENIDO diffgr:id="CONTENIDO2" msdata:rowOrder="1">
  <NOMBRE>A_USER2</NOMBRE>
  </CONTENIDO>

...

...

 

And I use the next code to try read it:

 

             var parser = new DOMParser();
             var xmlDoc = parser.parseFromString(xmlHttp.responseText, "text/xml");
             
             var root = xmlDoc.getElementsByTagName('DataSetGeneral')[1];
             var items = root.getElementsByTagName("CONTENIDO");
             for (var i = 0; i < items.length; i++)
             {
                 // get one item after another
                 var item = items[i];
                 // now we have the item object, time to get the contents
                 // get the name of the item
                 var name = item.getElementsByTagName("name")[0].firstChild.nodeValue;
                 // get the quantity
                 var quantity = item.getElementsByTagName("quantity")[0].firstChild.nodeValue;
                 alert("item #" + i + ": quantity=" + quantity);
             } // end of for

 

but give me error in line "var items = root.getElementsByTagName("CONTENIDO");"

 

Do you know why?

 

Thanks, Oscar

Re: read XML from WebService

[ Edited ]

 

var items = root.getElementsByTagName("CONTENIDO");

 

 

Edit the above line, try this...

 

var items = root[0].getElementsByTagName("CONTENIDO");
