The DOM tree creates a child for every entity reference. An interesting situation arises when an entity reference is embedded inside an XML string. Will the entity reference be a child of the whole XML string?
Let's look at an example. Here is the description element from our mydvd example:
<description>Sales Report for January, February,
and <&month;> of 2001</description>
The DOM tree splits the text of this description element to three nodes:
- Up to the entity reference:
"Sales Report for January, February, and <"
Entity reference: April
Trail: "< of 2001"
Let's show that indeed this is the case. First, we find the list of description objects:
objNodeList = xmlDoc.getElementsByTagName("description");
Our description is the first and only instance, so its index is 0. The following script prints the text values of description's three children:
alert(objNodeList(0).childNodes(0).text);
alert(objNodeList(0).childNodes(1).text);
alert(objNodeList(0).childNodes(2).text);
When running this script, you should get the three strings above.
