I'm trying to parse a document with a namespace declared on a non-root element:
<root><example:foo xmlns:example="http://example.com/foo";>This is an
exemplary foo!</example:foo></root>
I can read this xml into an NSXMLDocument just fine, but the following
XPath query on root returns a non-nil, but empty NSArray:
NSXMLNode *rootNode = ...// create my root node somehow
NSArray *exampleFooElements = [rootNode
nodesForXPath:@"/root/example:foo" error:nil];
// exampleFooElements != nil && [exampleFooElements count] == 0
However, if I add the namespace declaration to the root element,
everything is fine:
<root xmlns:example="http://example.com/foo";><example:foo>This is an
exemplary foo!</example:foo></root>
NSXMLNode *rootNode = ...// create my root node somehow
NSArray *exampleFooElements = [rootNode
nodesForXPath:@"/root/example:foo" error:nil];
// exampleFooElements != nil && [exampleFooElements count] == 1
I can do this change programmatically, but I'd rather not have to
modify the document. This namespace usage should be legal. Am I
doing something wrong?
Thanks!
