get attribute values from returned XML - iphone

This is the xml I am getting from web:
<?xml version="1.0"?>
<abc>87C4A556-B7E5-5AE4-81FE-86BE0C6306E1</abc>
<abc2>P29077758</abc2>
<abc3>55AGD99D</abc3>
<abc4>147</abc4>
<abc5>1286259226</abc5>
<abc6>USA</abc6>
<abc7>US</abc7>
and using this to get attribute:
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if( [elementName isEqualToString:#"a"])
{
recordResults = FALSE;
// greeting.text = soapResults;
[soapResults release];
soapResults = nil;
}
}
Something like that, but I don't have any idea how can I get attribute from returned xml and assign those returned variables into my created variable. How can I do this?

I highly recommend using TouchXML to do your XML parsing.
I personally had all kinds of issues with NSXMLParser and ended up using TouchXML. Works a treat!

You should implement the following methods:-
One way you can use is :-
(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
attributes:(NSDictionary *)attributeDict
{
//check that the element is the one you want. If it is then initialize the string in which you want to store the value.
if(elementName isEqualToString:#"abc")
{
tempString = [[NSMutableString alloc] init];
}
}
(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
[tempString appendString:string];
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
if(elementName isEqualToString:#"abc")
{
self.StringToStore = tempString;
}
}

Is possible parsing xml file that contains only one node by using NSXMLParser

As a beginner, I have read about NSXMLParser and try to implement a parser for parsing an xml
<?xml version="1.0" encoding="UTF-8"?>
<a>Some text here</a>
my implementation
-(OneNodeXMLParser*)initOneNodeXMLParser{
appDelegate = (OneNodeXMLParser*)[[UIApplication sharedApplication]delegate];
return self;
}
-(void)parser:(NSXMLParser*) parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
NSLog(#"%s",__PRETTY_FUNCTION__,nil);
if([elementName isEqualToString:#"a"]){
// init some varibles
}
NSLog(#"Starting processing");
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
NSLog(#"%s",__PRETTY_FUNCTION__,nil);
NSLog(#"%s",string);
}
-(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
NSLog(#"%s",__PRETTY_FUNCTION__,nil);
NSLog(#"Finishing processing");
}
What should I modify to parse the file successfully?
In your .h file declare a NSMutableString *store;
And change the following methods like:
-(void)parser:(NSXMLParser*) parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"a"])
{
store = [[NSMutableString alloc] init];
}
NSLog(#"Starting processing");
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
NSLog(#"%s",string);
if (store != nil)
{
[store appendString:string];
}
}
-(void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
NSLog(#"Finishing processing String : %#", store);
}
You can use that string variable store for future use.

how to get the values from the XML

I wants use google weather api in my project. here I am struggling from long time. to get the current temperature. city, humidity,day of week etc
I successfully hit the url. but I not know exact what i do in foundCharacter method to fetch the value.
Thanks
- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
if ([elementname isEqualToString:#"weather"])
{
currentTweet = [Tweet alloc];
}
}
- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
if ([elementname isEqualToString:#"city"])
{
}
}
Please check the code:
- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ([elementname isEqualToString:#"weather"])
{
currentTweet = [Tweet alloc];
}
else if ([elementname isEqualToString:#"city"])
{
currentTweet.city = [attributeDict valueForKey:#"city"]
}
}
- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if ([elementname isEqualToString:#"weather"])
{
NSLog("Current City: %#",currentTweet.city);
}
}
For this type of xml, you don't want to use the parser:foundCharacters:
Quote from NSXMLPareser reference guide about foundCharacters method:
Sent by a parser object to provide its delegate with a string
representing all or part of the characters of the current element.
The parser object may send the delegate several
parser:foundCharacters: messages to report the characters of an
element. Because string may be only part of the total character
content for the current element, you should append it to the current
accumulation of characters until the element changes.
For more details: NSXML Parser Reference,
Working of parser,foundCharacters use

How to parse XML Attributes with XMLParser delegates

getting pretty despirate here.. how on earth do I parse xml that have attributes in them.. I am completely lost,
this is what the xml that I am trying to parse looks like..
<Rows>

<Row SKATERID="318" MANUFACTURER="A.R.E." ISFACT="F" ISSKATE="T"/>
//...
</Rows>
Using your NSXMLParser Delegate method:
Updated my code. Here is the code which parses your XML.
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"Row"])
{
myAttrDict = [[NSDictionary alloc] initWithDictionary:attributeDict];
}
if([elementName isEqualToString:#"Rows"]
{
rowsArray = [[NSMutableArray alloc] init];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if([elementName isEqualToString:#"Row"])
{
[rowsArray addObject:myAttrDict];
[myAttrDict release],myAttrDict = nil;
}
}
- (void)parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(#"Rows Array: %#",rowsArray);
}

How do I parse this SOAP response in my iPhone application?

I am getting SOAP response and when parsing the response I am getting this: (As you can see from result which is currently stored as NSString is NSLoged itself contain xml format data)
<Menus>
<Table1>
<Restaurant_Name>CHICK-FIL-A</Restaurant_Name>
<Restaurant_id>2748</Restaurant_id>
<Phone>(404) 371-1466</Phone>
<billing_city>DECATUR</billing_city>
<billing_state>GA</billing_state>
<billing_zip_code>30030</billing_zip_code>
<billing_addr1>105 EAST TRINITY PLACE</billing_addr1>
</Table1>
</Menus>
The Code for the above generated response:
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict{
if([elementName isEqualToString:#"GetMenusByZipCodeResult"])
{
if(!soapResults)
{
soapResults = [[NSMutableString alloc] init];
}
recordResults = TRUE;
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if(recordResults)
{
[soapResults appendString:string];
}
//NSLog(#" soap: %#", soapResults);
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
{
if([elementName isEqualToString:#"GetMenusByZipCodeResult"])
{
NSLog(#"soapResult FINAL : %#",soapResults);
recordResults = FALSE;
result.text = soapResults;
[soapResults release];
soapResults = nil;
}
}
The above mention data is result of soapResult.
How to read this data? I tried to reparse it but it is not helping.
Please help me.
If you want a simple XML to NSDictionary converter (including the text nodes), check out http://troybrant.net/blog/2010/09/simple-xml-to-nsdictionary-converter/

how to get all values using NSXML parser on iphone

i can only parse 1st element of this xml but i want to get all the content of cuisine
this is my xml
<cuisines>
<cuisine>Asian</cuisine>
<cuisine>Nepalese</cuisine>
<cuisine>North Indian</cuisine>
<cuisine>Indian Vegetarian</cuisine>
<cuisine>Organic Cuisine</cuisine>
</cuisines>
and this is the code to parse
if ( [elementName isEqualToString:#"cuisines"]) {
if ( [elementName isEqualToString:#"cuisine"] ) {
elementName=[[NSMutableString alloc] init];
keyInProgress = [elementName copy];
// This is a string we will append to as the text arrives
textInProgress = [[[NSMutableString alloc] init]autorelease];
return;
}
but its not working i want to get all the value
you need to implement the parser method as well as the following NSXMLParserDelegate protocol methods methods:
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
