Issues querying google sitemap.xml with Linq to XML
I have a Linq-2-XML query that will not work if a google sitemap that I have created has its urlset element populated with attributes but will work fine if there are no attributes present.
Can't query:
<?xml version="1.0" encoding="utf-8"?>
<urlset 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"
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>http://www.foo.com/index.htm</loc>
<lastmod>2010-05-11</lastmod>
<changefreq>monthly</changefreq>
<priority>1.0</priority>

</url>
</urlset>
Can query:
<?xml version="1.0" encoding="utf-8"?>
<urlset>
<url>
<loc>http://www.foo.com/index.htm</loc>
<lastmod>2010-05-11</lastmod>
<changefreq>monthly</changefreq>
<priority>1.0</priority>

<lastmod>2010-05-11</lastmod>
<changefreq>monthly<开发者_开发问答;/changefreq>
<priority>1.0</priority>
</url>
</urlset>
The query:
XDocument xDoc = XDocument.Load(@"C:\Test\sitemap.xml");
var sitemapUrls = (from l in xDoc.Descendants("url")
select l.Element("loc").Value);
foreach (var item in sitemapUrls)
{
Console.WriteLine(item.ToString());
}
What would be the reason for this?
See the "xmlns=" tag in the XML? You need to specify the namespace. Test the following modification of your code:
XDocument xDoc = XDocument.Load(@"C:\Test\sitemap.xml");
XNamespace ns = "http://www.sitemaps.org/schemas/sitemap/0.9";
var sitemapUrls = (from l in xDoc.Descendants(ns + "url")
select l.Element(ns + "loc").Value);
foreach (var item in sitemapUrls)
{
Console.WriteLine(item.ToString());
}
