MSXML中 validateOnLoad 和 validateOnParse 有什么区别啊

[zhghl]

多谢指点,应该怎么用呢,能否举个例子.

validateOnLoad例子：

Set oSchemaCache = CreateObject("Msxml2.XMLSchemaCache.4.0")
Set oAnnotationDoc = CreateObject("Msxml2.DOMDocument.4.0")

' Load the schema.
nsTarget="http://www.example.microsoft.com/po"

' Setting validateOnLoad to true is optional; true is the default value.
oSchemaCache.validateOnLoad = true
oSchemaCache.add "urn1", schema1 ' Validated on add.
oSchemaCache.add "urn2", schema2 ' Validated on add.
oSchemaCache.validateOnLoad = false
oSchemaCache.add "urn3", schema3 ' Not validated yet.
oSchemaCache.add "urn4", schema4 ' Not validated yet.
' Schema3 and schema4 are validated now. Schema1 and schema2 are not validated now, because they already were.

oSchemaCache.validate

validateOnParse 例子：

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
xmlDoc.async = false;
xmlDoc.validateOnParse = true;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
var myErr = xmlDoc.parseError;
WScript.Echo("You have error " + myErr.reason);
}

validateOnParse
标明解析器是否要对文档进行验证


validateOnLoad

Indicates whether the schema will be compiled and validated when it is loaded into the schema cache. The validateOnLoad Property must be set to false before any schemas that are not to be validated are loaded into the schema cache.
