I have an XML file like this :

XML

<item>  
  <title>...</title>  
  <link>...</link>    
  <pubDate>...</pubDate>
  <description>...</description>
  <media:content url=" ....." type="image/jpg" medium="image" height="270" width="480" />
</item>

I want to get attribute url in media:content tag.
But I don't know how to do this?
I only get <title>, <link>, <pubDate>, <description> using DOM Parser.

Please help me! Thanks and best regard!!!

This is not an Android issue but an XML issue. The XML element you are trying to reference contains a namespace i.e. media. You need to import the XML namespace before you can reference it.

I'm not entirely sure how you achieve this in Java (I'm assuming you are doing this in Java) but in C# the code would be similar to the following.

XNamespace nsMedia = "media"; //the actual namespace may be at the top of the XML document
foreach (XElement xItem in xItems.Elements("item"))
{
  XElement xContent = xItem.Element(nsMedia + "content"); 
  XAttribute xUrl = xContent.Attribute("url");
  string url = xUrl.Value;
}

The media:content node name means that this node is part of the XML namespace which is currently using the alias "media".

Somewhere in your document, you should see the namespace declaration:

XML

<someNode xmlns:media="..."

(If you don't, then the XML is malformed.)

According to this SO thread[^], you should call setNamespaceAware(true) on your DocumentBuilderFactory object, and use the getElementsByTagNameNS method to read the elements.
