文章摘要

这篇文章讨论了在XMLDOMElement中处理属性的方法，强调了属性作为节点而非子节点的特性。文章详细介绍了三种属性操作方式：直接通过`getAttribute`和`setAttribute`方法，通过属性节点的`getAttributeNode`和`setAttributeNode`方法，以及以属性集合形式访问和赋值的方法。文章还提供了JScript和VBScript示例代码，展示了如何在不同语言中实现属性的创建和赋值。此外，文章还提到，当需要处理包含实体引用的属性时，必须使用属性节点和文本节点的方法。通过这些方法，可以在不同编程语言和环境中有效地处理XML文档中的属性。

Although attributes belong to a particular element, they are not considered child nodes of element nodes. Instead, they behave more like properties of IXMLDOMElement.

Most of the methods for working with attributes come from IXMLDOMElement. Attributes can be manipulated in the following ways.

Directly, through the getAttribute and setAttribute methods of IXMLDOMElement.

As named IXMLDOMAttribute nodes, with getAttributeNode and setAttributeNode.

As a set of nodes accessible through the attributes property and returned as an IXMLNamedNodeMap.

Examples

JScript

The following JScript example creates a new document containing a element, and then creates an attribute named author with a value of “Pat Coleman”.

复制代码代码如下:

var xmlDoc=new ActiveXObject(“Msxml2.DOMDocument.3.0”);

var rootElement=xmlDoc.createElement(“memo”);

rootElement.setAttribute(“author”, “Pat Coleman”);

xmlDoc.appendChild(rootElement);

VBScript

复制代码代码如下:

Set xmlDoc=CreateObject(“Msxml2.DOMDocument.3.0”)

Set rootElement=xmlDoc.createElement(“memo”)

rootElement.setAttribute(“author”, “Pat Coleman”)

xmlDoc.appendChild(rootElement)

If you prefer to work with attribute nodes, you can create the attribute, and then create a text node to store its value. Attribute nodes can only contain text nodes and entity reference nodes. (If you need to create an attribute containing an entity reference, you must use this approach.)

Working with attribute nodes requires using the DOMDocument object to create attribute and text (and entity reference, if necessary) nodes before assigning the nodes to the element.

JScript

The following JScript code uses this approach to perform the same work as the preceding examples, creating a element with an author attribute holding the value “Pat Coleman”.

复制代码代码如下:

var xmlDoc=new ActiveXObject(“Msxml2.DOMDocument.3.0”);

var rootElement=xmlDoc.createElement(“memo”);

var memoAttribute=xmlDoc.createAttribute(“author”);

var memoAttributeText=xmlDoc.createTextNode(“Pat Coleman”);

memoAttribute.appendChild(memoAttributeText);

rootElement.setAttributeNode(memoAttribute);

xmlDoc.appendChild(rootElement);

VBScript

复制代码代码如下:

Set xmlDoc=CreateObject(“Msxml2.DOMDocument.3.0”)

Set rootElement=xmlDoc.createElement(“memo”)

Set memoAttribute=xmlDoc.createAttribute(“author”)

Set memoAttributeText=xmlDoc.createTextNode(“Pat Coleman”)

memoAttribute.appendChild(memoAttributeText)

rootElement.setAttributeNode(memoAttribute)

xmlDoc.appendChild(rootElement)
