使用xml：id属性时出现XmlSchemaValidationException [英] XmlSchemaValidationException when using xml:id attribute

问题描述

我有一个XML文件，它使用此处定义的xml：id特殊属性：
http://www.w3.org/TR/xml-id/ - 但是，当我尝试解析此XML时，我得到以下异常：

I have an XML file that uses the xml:id special attribute as defined here: http://www.w3.org/TR/xml-id/ -- however, when I try to parse this XML I get the following exception:

The 'http://www.w3.org/XML/1998/namespace:id' attribute is not declared.

Exception: System.Xml.Schema.XmlSchemaValidationException
   Message: The 'http://www.w3.org/XML/1998/namespace:id' attribute is not declared.

<有人能告诉我为什么会这样吗？以下是XML的相关部分：

Can anyone tell me why this is happening? Here's the relevant section of the XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<data
    xmlns="urn:x-KP:psp:merge"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<recipient xml:id="IM00011_171761_1" include="cover_zh enclosureA_zh enclosureB_zh cover_en enclosureA_en enclosureB_en">
		...
	</recipient>
</data>

推荐答案

基本上你需要提供架构（ http://www.w3.org/2004/10/xml.xsd ）定义该属性，或者您可以尝试使用AllowXmlAttributes标志进行验证
$启用b $ b http://msdn.microsoft.com/en-us/library/system.xml.schema.xmlschemavalidationflags.aspx 可以解决问题。我不确定该标志是否支持xml：id属性，它可能只支持xml：lang和xml：base和xml：space。

Basically you need to supply a schema (http://www.w3.org/2004/10/xml.xsd) defining that attribute or you can try whether validating with the AllowXmlAttributes flag http://msdn.microsoft.com/en-us/library/system.xml.schema.xmlschemavalidationflags.aspx being enabled fixes the problem. I am not sure however that flag supports the xml:id attribute, it might only support xml:lang and xml:base and xml:space.
