在XML属性上使用冒号字符时出错

Question

如何使用类XDocument并将其属性名称设置为接受冒号字符？我收到此错误

“该'：'字符，十六进制值0x3A，不能包含在名称中。”

Dim ns As XNamespace = "http://www.sitemaps.org/schemas/sitemap/0.9" 
Dim xi As XNamespace = "http://www.w3.org/2001/XMLSchema-instance" 

Dim sitemapValue As New XDocument(New XDeclaration("1.0", "utf-8", ""), 
New XElement("urlset", New XAttribute("xmls", ns), 
            New XAttribute("xmls:xi", xi))) 

我只是想下面使用的XDocument类下面的头输出。

<?xml version="1.0" encoding="UTF-8"?> 
<urlset 
     xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 
      http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">

Dim ns As XNamespace = "http://www.sitemaps.org/schemas/sitemap/0.9" 
Dim xi As XNamespace = "http://www.w3.org/2001/XMLSchema-instance" 

Dim sitemapValue As New XDocument(New XDeclaration("1.0", "utf-8", ""), New XElement("urlset", New XAttribute("xmls", ns), _ 
            New XAttribute(XNamespace.Xmlns + "xi", xi), New XAttribute(xi + "schemaLocation", "http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"))) 

输出：

<urlset xmls="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xi="http://www.w3.org/2001/XMLSchema-instance" xi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd" /> 

让我知道这是你问什么。

尝试（使用VS 2010，否则，你需要增加续行字符）

Dim ns As XNamespace = "http://www.sitemaps.org/schemas/sitemap/0.9" 
Dim xi As XNamespace = "http://www.w3.org/2001/XMLSchema-instance" 

Dim doc As XDocument = New XDocument(
         New XElement(ns + "urlset", 
            New XAttribute(XNamespace.Xmlns + "xsi", xi), 
            New XAttribute(xi + "schemaLocation", "http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd")))
