XML by Example

The <img> element object splits the text into two text objects:

• the text before the

<img> element “The element can contain text and

other elements such as images”

• and the text after “or other.”

2. In general, to retrieve the text of an element, it is safer to iterate over

the element’s children. Fortunately, because

getText() is isolated in a

separate function, it’s easy to replace:

function getText(node)

{

if(node.nodeType == 1)

{

var text = “”,

children = node.childNodes,

i;

for(i = 0;i < children.length;i++)

if(children.item(i).nodeType == 3)

text += children.item(i).data;

return text

}

else

return “”;

}

Managing the State

The previous example is very simple. ...
