Parsing xml NSData for iPhone Development

The xml string is:

<Users>
<User name = "hoge" age = "20"/>
<User name = "fuga" age = "30"/>
</Users>

 

// Parse button event

-(IBAction) btnXml

{

NSString * str = [uitextview1 text];

// Convert string to data

NSData * xmlData = [str dataUsingEncoding: NSUTF8StringEncoding];

// NSXMLParser class is required for xml parsing. First, an NSXMLParser object is declared.

// Start Parsing

NSXMLParser * xmlRead = [[NSXMLParser alloc] initWithData: xmlData]; // initialize the NSXMLParser object

[XmlRead setDelegate: self]; // sets the DNS proxy for the NSXMLParser object

[XmlRead parse]; // call the proxy to parse the NSXMLParser object and check whether the parsing is successful.

}

 

// Parser to read content from two nodes

-(Void) parser :( NSXMLParser *) parser foundCharacters :( NSString *) string {

// NSLog (@ "% @", string );}

 

 

// Obtain the end value of the node

-(Void) parser :( NSXMLParser *) parser didEndElement :( NSString *) elementName

NamespaceURI :( NSString *) namespaceURI qualifiedName :( NSString *) qName {

// NSLog (@ "% @", elementName );}

 

// Get the nod Value

-(Void) parser :( NSXMLParser *) parser didStartElement :( NSString *) elementName

NamespaceURI :( NSString *) namespaceURI qualifiedName :( NSString *) qName

Attributes :( NSDictionary *) attributeDict

{

// NSLog (@ "% @", elementName );

If ([elementName isEqualToString: @ "user"])

{

NSString * strName = [attributeDict valueForKey: @ "name"];

NSString * strAge = [attributeDict valueForKey: @ "age"];

NSString * strUser = uitextview2.text;

StrUser = [strUser stringByAppendingFormat: @ "Name: % @, age: % @ \ n", strName, strAge];

[Uitextview2 setText: strUser];

// NSLog (@ "Name: % @, age: % @", strName, strAge );

}

}
