An NSXMLParser wrapper for converting XML to NSDictionary with blocks and background threading.
- Based on powerful built-in
NSXMLParser - Asynchronous parsing and completion block with resulting
NSDictionaryorNSError - Background threading for not blocking UI while parsing
- Adding attibutes as key-value pairs after prefixing keys with
-to prevent collision - Converting repeating elements to proper arrays
- Handling inner texts among tags as an array using
-InnerTextkey - Excluding comments in resulting
NSDictionary
- With XML data as
NSData
NSData* XMLData = [Read from disk or fetch from network];
[EYXML2NSDictionary parseXMLData:XMLData completion:^(NSDictionary* dict, NSError* error)
{
if (!error)
NSLog(@"Result: %@", dict);
else
NSLog(@"Error: %@", error);
}];
- With XML string as
NSString
NSString* XMLString = @""
"<message>"
" <to>A</to>"
" <from>B</from>"
" <title >Fourth Title</title>"
" <body>"
" This is meessage body."
" <attachment>Attachment 1</attachment>"
" </body>"
"</message>";
[EYXML2NSDictionary parseXMLString:XMLString completion:^(NSDictionary* dict, NSError* error)
{
if (!error)
NSLog(@"Result: %@", dict);
else
NSLog(@"Error: %@", error);
}];
- Input
<message>
<to>A</to>
<from>B</from>
<title anAttribute = 'a1' anotherAttribute = 'a2'>First Title</title>
<title anAttribute = 'b1' anotherAttribute = 'b2'>Second Title</title>
<title >Third Title</title>
<title >Fourth Title</title>
<body>
