Removing an XML Element with the same name

[John Paul Hoey]

Hi All,

I was wondering if someone could help me with my query please.

I have the following XML elements within my XML document:

<AddressLines>
<AddressLine>143</AddressLine>
<AddressLine>Fork Street</AddressLine>
<AddressLine>East Calder</AddressLine>
<AddressLine>Lothian</AddressLine>
<AddressLine>Scotland</AddressLine>
</AddressLines>

What i want to do is delete ONLY the third element from the XML above, without affecting the other address lines within the XML, however unfortunately, i cant seem to figure out how to do this.

As an example, when i want to remove a node which contains one element from my XML document then i use the following code; this works successfully:

Node output_FirstName = (Node) FirstName.evaluate(doc, XPathConstants.NODE);
output_FirstName.getParentNode().removeChild(output_FirstName);

Also, when i want to add text to the third element of the above XML, i use a NodeList contained within the following method; again this works successfully:

Document Org_Address3 (Document doc, String AddressLine3) {
          
  //==============
  //Set Address 3
  //==============
                        
  XPathFactory factory_AddressLine3 = XPathFactory.newInstance();
  XPath xpath_AddressLine3 = factory_AddressLine3.newXPath();
  XPathExpression Org_AddressLine3 = xpath_AddressLine3.compile("//Organisation/Address/AddressLines/AddressLine");

  Object output_AddressLine3 = Presc_AddressLine3.evaluate(doc, XPathConstants.NODESET);
  NodeList nodes_AddressLine3 = (NodeList) output_AddressLine3;
  nodes_AddressLine3.item(2).setTextContent(AddressLine3);
            
  Document Doc1 = doc;
                        
  return Doc1;

}

However as prevously stated, i just cant seem to figure out how to remove only one element from the above XML example.

I tried looping through the NodeList and then deleting the item i want to remove however i cant seem to get this to work; im also not sure if this is the best approach either.

Any help in this matter would be very much appreciated.

Thanks in advance

John

Hi all,

Ive managed to figure this out therefore you can ignore this question - however ill post in the off chance anyone else needs to know

I found that i can use the .getElementsByTagName method with my XML document object which allows me to allocate a specific element item in the list, therefore i didnt need to use a NodeList.

Here is the code i used:

Document Det_Address3 (Document doc, String AddressLine3) {
          
            
                        //=================
                        // Remove Address 3
                        //=================
                        
                        XPathFactory factory_AddressLine3 = XPathFactory.newInstance();
                        XPath xpath_AddressLine3 = factory_AddressLine3.newXPath();
                        XPathExpression Presc_AddressLine3 = xpath_AddressLine3.compile("//Organisation/Address/AddressLines/AddressLine");

                        Node output_AddressLine3 = (Node) Presc_AddressLine3.evaluate(doc, XPathConstants.NODE);
                        Node output_AddressLine3_Final = doc.getElementsByTagName("AddressLine").item(2);
                        output_AddressLine3.getParentNode().removeChild(output_AddressLine3_Final); 
            
                        Document Doc1 = doc;
                        
                        return Doc1;
            
            
             }

Thanks

John
