Question

我需要生成如下所示的XML：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <url>
        <loc>http://www.xyz.eu/</loc>
        <lastmod>2010-01-20T10:56:47Z</lastmod>
        <changefreq>daily</changefreq>
        <priority>1</priority>
    </url>
    <url>
        <loc>http://www.xyz.eu/2/</loc>
        <lastmod>2009-10-13T10:20:03Z</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.5</priority>
    </url>
    <url>
        <loc>http://www.xyz.eu/3/</loc>
        <lastmod>2009-10-13T10:19:09Z</lastmod>
        <changefreq>daily</changefreq>
        <priority>0.5</priority>
    </url>
</urlset>

我似乎无法弄清楚如何在没有名称的情况下添加名称空间而不在所有url标记中添加'xmlns =“”'。

我的代码：

XNamespace blank = XNamespace.Get(@"http://www.sitemaps.org/schemas/sitemap/0.9");
XNamespace xsi = XNamespace.Get(@"http://www.w3.org/2001/XMLSchema-instance");

XDocument doc = new XDocument(
    new XDeclaration("1.0", "utf-8", "yes"),
    new XElement(blank + "urlset",
        //new XAttribute(XNamespace.Xmlns +"", blank),
        new XAttribute(XNamespace.Xmlns + "xsi", xsi),
        // This private method loops through the dictionary and creates all the page nodes

        GetSiteMapChildren(pageIdVersionDic, site.Url)             
     ));

有什么想法吗？感谢

您需要将“空白”命名空间声明为默认命名空间。例如，这很好用：

        XNamespace blank = XNamespace.Get(@"http://www.sitemaps.org/schemas/sitemap/0.9");
        XNamespace xsi = XNamespace.Get(@"http://www.w3.org/2001/XMLSchema-instance");

        XDocument doc = new XDocument(
            new XDeclaration("1.0", "utf-8", "yes"),
            new XElement(blank + "urlset",
                new XAttribute("xmlns", blank.NamespaceName), 
                new XAttribute(XNamespace.Xmlns + "xsi", xsi.NamespaceName),

                new XElement(blank + "url",
                    new XElement(blank + "loc", "http://www.xyz.eu/"),
                    new XElement(blank + "lastmod", "2010-01-20T10:56:47Z"),
                    new XElement(blank + "changefreq", "daily"),
                    new XElement(blank + "priority", "1"))
             ));

        Console.WriteLine(doc.ToString());

将带有和不带名称的名称空间添加到XElement
