I'm parsing an XML feed that looks something like this:
<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:cc="http://web.resource.org/cc/" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" xmlns:media="http://search.yahoo.com/mrss/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<channel>
...
</channel>
</rss>
One thing I wanted to do was get all the namespaces by URL and get the associated prefix for later parsing. For example, if I know the itunes DTD is located at: http://www.itunes.com/dtds/podcast-1.0.dtd I want to get the associated prefix. Here is some code I want to use to do that:
if(parser.getEventType() != START_TAG && !"rss".equalsIgnoreCase(parser.getName())) {
throw new IllegalStateException();
}
for(int i=0; i<parser.getAttributeCount(); i++) {
if(!"xmlns".equalsIgnoreCase(parser.getAttributePrefix(i))) {
continue;
}
String namespace = parser.getAttributeName(i);
String namespaceUrl = parser.getAttributeValue(i);
if(namespaceUrl.contains("www.itunes.com")) {
ITUNES_NAMESPACE = namespace;
} else if(namespaceUrl.contains("www.w3.org/2005/Atom")) {
ATOM_NAMESPACE = namespace;
}
}
However, the only attribute that shows up here is the rss "version" attribute (getAttributeCount returns 1 and the name and values for "version" and "2.0"). Is there some way to get the namespaces?
