Question

When I try to traverse to the children of the gallery node, it return nothing for the nodevalue, when it should read ‘Joe Bloggs’, and ‘#text’ for the node name when it should read ‘property’. Can anyone see what might be wrong with my javascript or XML.

<gallery_index>
  <gallery id="0">
     <property id="name">Joe Bloggs</property>
     <property id="description"><p>testtest</p></property>
     <property id="thumbnail_path">/images/thumb.jpg</property>
     <property id="weblink">http://www.cnn.com</property>
     <property id="client"></property>
     <assets/>
  </gallery>
</gallery_index>

Javascript.

// code for IE
 if (window.ActiveXObject){
  xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
 }
 // code for Mozilla, Firefox, Opera, etc.
 else if (document.implementation.createDocument)
 {
 xmlDoc=document.implementation.createDocument("","",null);
 }
 else
 {
 alert('Your browser cannot handle this script');
 }
 xmlDoc.async=false;
 xmlDoc.load("../../../../../../../../xml/gallery_index.xml");

 galleryIndexNode = xmlDoc.documentElement;
 galleryNode = galleryIndexNode.firstChild;

 alert(galleryNode.firstChild.nodeName);

EDIT:

OK, changed the following javascript. The nodeName and nodeValue will display if I do this.

alert(galleryNode.childNodes[1].nodeName);

alert(galleryNode.childNodes[3].nodeName);

Is my XML badly formed? It displays in FF fine. What can i do to fix this?

Answer 1

The first child of <gallery> in your example is a text node with nothing in it (or a line break and some tabs, depending on whether whitespace is preserved by your parser). The element containing Joe Bloggs is the second child of <gallery>.

In fact, by the look of it, galleryNode in your script points to the first text child of <gallery_index>, rather than the <gallery> element.
