DEVELOPING COLDFUSION 9 APPLICATIONS

Using Web Elements and External Objects

DOM node view

The DOM node view presents the XML document object using the same format as the document's XML Document

Object Model (DOM). In fact, an XML document object is a representation of a DOM object.

The DOM is a World Wide Web Consortium (W3C) recommendation (specification) for a platform- and language-

neutral interface to dynamically access and update the content, structure, and style of documents. ColdFusion

conforms to the DOM Level 2 Core specification, available at www.w3.org/TR/DOM-Level-2-Core.

In the DOM node view, the document consists of a hierarchical tree of nodes. Each node has a DOM node type, a node

name, and a node value. Node types include Element, Comment, Text, and so on. The DOM structures the document

object and each of the elements it contains into multiple nodes of different types, providing a finer-grained view of the

document structure than the basic view. For example, if an XML comment is in the middle of a block of text, the DOM

node view represents its position in the text while the basic view does not.

ColdFusion also lets you use the DOM objects, methods, and properties defined in the W3C DOM Level 2 Core

specification to manipulate the XML document object.

For more information on referencing DOM nodes, see

does not cover the node view and using DOM methods and properties in detail.

XML document structures

An XML document object is a structure that contains a set of nested XML element structures. The following image

shows a section of the

page 1059. This image shows the long version of the dump, which provides complete details about the document

object. Initially, ColdFusion displays a short version, with basic information. Click the dump header to change between

short, long, and collapsed versions of the dump.

The following code displays this output. It assumes that you save the code in a file under your web root, such as

C:\Inetpub\wwwroot\testdocs\employeesimple.xml

<cffile action="read" file="C:\Inetpub\wwwroot\testdocs\employeesimple.xml"

variable="xmldoc">

The document object structure

At the top level, the XML document object has the following three entries:
