我有以下类用于生成网站地图:
public class SitemapItem
{
public SitemapItem(string url)
{
this.Url = url;
this.AlternateLinks = new List<SiteMapAlternateLink>();
}
public string Url { get; set; }
public DateTime? LastModified { get; set; }
public ChangeFrequency? ChangeFrequency { get; set; }
public float? Priority { get; set; }
public List<SiteMapAlternateLink> AlternateLinks { get; set; }
}
并且:
public class SiteMapAlternateLink
{
public SiteMapAlternateLink(string url, string language)
{
this.Url = url;
this.Language = language;
}
public string Url { get; set; }
public string Language { get; set; }
}
现在,在我的控制器中,我使用以下代码填充SitemapItems列表,并从控制器返回它:
public class XmlSitemapResult : ActionResult
{
private XNamespace nsSitemap = "http://www.sitemaps.org/schemas/sitemap/0.9";
private XNamespace nsXhtml = "http://www.w3.org/1999/xhtml";
private IEnumerable<SitemapItem> _items;
public XmlSitemapResult(IEnumerable<SitemapItem> items)
{
_items = items;
}
public override void ExecuteResult(ControllerContext context)
{
string encoding = context.HttpContext.Response.ContentEncoding.WebName;
XDocument sitemap = new XDocument(new XDeclaration("1.0", encoding, "yes"),
new XElement(nsSitemap + "urlset", new XAttribute(XNamespace.Xmlns + "xhtml", nsXhtml),
from item in _items
select CreateItemElement(item)
)
);
context.HttpContext.Response.ContentType = "application/xml";
context.HttpContext.Response.Charset = encoding;
context.HttpContext.Response.Flush();
context.HttpContext.Response.Write(sitemap.Declaration + sitemap.ToString());
}
private XElement CreateItemElement(SitemapItem item)
{
XElement itemElement = new XElement(nsSitemap + "url", new XElement(nsSitemap + "loc", item.Url.ToLower()));
if (item.LastModified.HasValue)
itemElement.Add(new XElement(nsSitemap + "lastmod", item.LastModified.Value.ToString("yyyy-MM-dd")));
if (item.ChangeFrequency.HasValue)
itemElement.Add(new XElement(nsSitemap + "changefreq", item.ChangeFrequency.Value.ToString().ToLower()));
if (item.Priority.HasValue)
itemElement.Add(new XElement(nsSitemap + "priority", item.Priority.Value.ToString(CultureInfo.InvariantCulture)));
foreach (var alternateLink in item.AlternateLinks)
{
itemElement.Add(new XElement(nsXhtml + "link",
new XAttribute("rel", "alternate"),
new XAttribute("hreflang", alternateLink.Language),
new XAttribute("href", alternateLink.Url)));
}
return itemElement;
}
}
现在的问题是,我的浏览器中看不到 XML 的原始格式,而只能看到文本内容,无法使用标准的 XML 查看器查看。这种情况在所有浏览器中都出现过,似乎是在添加 xhtml 模式后发生的。
希望有人能解决这个问题,谢谢!
编辑:如果删除与 xhtml 有关的内容,则浏览器可以将其显示为 xml。有什么想法吗?
