how to retrieve data from records in XML

Question

I have a XML:

<Name id="Name" dataType="java.lang.String" perDataProId="">Peter</Name>
 <Grid1 id="Grid1">
   <records>
     <record id="Grid1_0">
        <item id="department" dataType="java.lang.String" perDataProId="">PUR</item>
     </record>
    <record id="Grid1_1">
        <item id="department" dataType="java.lang.String" perDataProId="">SALE</item>
     </record>
   </records>
</Grid1> 

I can get the Name tag text using:

if (dom.getElementsByTagName("Name").length!=0){
       name=  dom.getElementsByTagName("Name")[0].childNodes[0].nodeValue;        
  }

but how to get the item department's value? I have tried dom.getElementsByTagName("Grid1_0").length and the result is 0. Can anyone help me with this ?

Answer 1

在这种情况下，您可以使用getElementById通过id获取元素，即：

dom.getElementById('Grid1_0')
