There are a couple of "bugs" in the schema location parsing
if the attribute does not contain the expected tokens:
public static String getSchemaLocation(Attributes attrs, String nsUri)
{
String location = null;
String schemaLocation = attrs.getValue(XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI, "schemaLocation");
if(schemaLocation != null)
{
StringTokenizer tokenizer = new StringTokenizer(schemaLocation, " \t\n\r");
String ns = tokenizer.nextToken();
while(ns != null)
{
location = tokenizer.nextToken(); // Comment: Oops no next token
if(ns.equals(nsUri))
{
break;
}
ns = tokenizer.nextToken();
}
}
// Comment: Returns the last "location" even if the namespace didn't match?
// Is that intentional?
return location;
}
I would implement it like this:
public static String getSchemaLocation(Attributes attrs, String nsUri)
{
String schemaLocation = attrs.getValue(XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI, "schemaLocation");
if (schemaLocation != null)
{
StringTokenizer tokenizer = new StringTokenizer(schemaLocation, " \t\n\r");
while (tokenizer.hasMoreTokens())
{
String namespace = tokenizer.nextToken();
if (namespace.equals(nsUri) && tokenizer.hasMoreTokens())
return tokenizer.nextToken();
}
}
return null;
}
