如何创建XmlElement的前缀属性？ [英] How to create XmlElement attributes with prefix?

问题描述

我需要能够定义与在一个xml元素的前缀的属性

I need to be able to define an attribute with a prefix in a xml element.

有关实例...

<nc:Person s:id="ID_Person_01"></nc:Person>

在为了做到这一点，我虽然，以下会工作。

In order to do this I though that the following would have worked.

XmlElement TempElement = XmlDocToRef.CreateElement("nc:Person", "http://niem.gov/niem/niem-core/2.0");
TempElement.SetAttribute("s:id", "http://niem.gov/niem/structures/2.0", "ID_Person_01");

不幸的是，XmlElement.SetAttribute（字符串，字符串，字符串）似乎并不支持解析前缀我收到以下错误

Unfortunately, XmlElement.SetAttribute(string, string, string) does not seem to support parsing the prefix as I receive the error below.

在'：'字符，十六进制值0x3A，不能包含在$名称

The ':' character, hexadecimal value 0x3A, cannot be included in a name.

我将如何定义与前缀属性？

推荐答案

如果你已经宣布根节点的命名空间，你只需要修改的setAttribute 呼叫使用加前缀的属性名称。所以，如果你的根节点定义这样一个命名空间：

If you've already declared your namespace in the root node, you just need to change the SetAttribute call to use the unprefixed attribute name. So if your root node defines a namespace like this:

<People xmlns:s='http://niem.gov/niem/structures/2.0'>

您可以做到这一点，该属性将拿起你已经建立了前缀：

You can do this and the attribute will pick up the prefix you've already established:

// no prefix on the first argument - it will be rendered as
// s:id='ID_Person_01'
TempElement.SetAttribute("id", "http://niem.gov/niem/structures/2.0", "ID_Person_01");

如果您还没有声明的名称空间（和它的前缀），三串的 XmlDocument.CreateAttribute 超载​​会为你做它：

If you have not yet declared the namespace (and its prefix), the three-string XmlDocument.CreateAttribute overload will do it for you:

// Adds the declaration to your root node
var attribute = xmlDocToRef.CreateAttribute("s", "id", "http://niem.gov/niem/structures/2.0");
attribute.InnerText = "ID_Person_01"
TempElement.SetAttributeNode(attribute);
