Updating XML file using DOM parser

Question

Hi,
Can someone help me, how to update following XML file using DOM parser.
The following is my XML file.
<students>
     <student>
          <id>1</id>
          <name>abc</name>
     </student>
     <student>
          <id>2</id>
          <name>xyz</name>
     </student>
     <student>
          <id>3</id>
          <name/>
     </student>
     <student>
          <id>4</id>
          <name>ijk</name>
     </student>
     <student>
          <id>5</id>
          <name></name>
     </student>
</students>Consider, I will input 2 fields, ie., id & name. For the matching Id, the name has to be updated.
Though, I have achieved this, but I am unable to update the value for 3rd record, & 5th record ie., id=3 & id=5. Since, these are blank.
Thanks.

Answer 1

Some <name> elements have a child node which is a text node. From what you say it appears you know how to change those text nodes.
The other <name> elements don't have any child nodes. But you want one. This suggests to me that you need code that creates a text node and adds it to the <name> element as its child.
