You can create entity references on the fly. Remember our date element from mydvd7.xml:
<date>Jan 30, 2002</date>
Let's add an entity reference for the day of the week, before the date. We have already prepared the substitution in the DTD file:
<!ENTITY day "Wednesday, ">
First, let's create the entity reference node:
var newEntityReference = xmlDoc.createEntityReference("day");
Find the first and only date element:
objNodeList = xmlDoc.getElementsByTagName("date");
Now, insert the new node as a child of the date element, before its first child, the text: Jan 30, 2002:
objNodeList(0).insertBefore(newEntityReference, objNodeList(0).childNodes(0));
Let's verify now that the date element has two children: "Wednesday, " and "Jan 30, 2002". The following lines print these two nodes, as well as the child of the entity reference:
alert(objNodeList(0).childNodes(0).text); alert(objNodeList(0).childNodes(1).text); alert(objNodeList(0).childNodes(0).childNodes(0).text);
Running this script will yield the two expected results. But notice that the entity reference has its own child which is also "Wednesday, ".
