现在请大家有没有人帮忙找了，我怎么可以从使用XML数据的URL NSXMLParser或任何其他XML解析器假设TBXML在IOS？
编辑：你也可以给我举例libxml解析这个XML。
提前致谢。
试试这一个
- (void)viewDidLoad
{
NSURL *url = [[NSURL alloc]initWithString:@"yourURL"];
NSXMLParser *parser = [[NSXMLParser alloc]initWithContentsOfURL:url];
[parser setDelegate:self];
BOOL result = [parser parse];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict
{
NSLog(@\"Did start element\");
if ( [elementName isEqualToString:@"root"])
{
NSLog(@"found rootElement");
return;
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
NSLog(@"Did end element");
if ([elementName isEqualToString:@"root"])
{
NSLog(@"rootelement end");
}
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
NSString *tagName = @"column";
if([tagName isEqualToString:@"column"])
{
NSLog(@"Value %@",string);
}
}
好吧，你问一个libxml例子。 我用它在一个项目，但与TBXML代替NSXMLParser因为这个引起编码和数据检索的重要问题。
首先，你必须下载TBXML.m和TBXML.h从网页文件，并将其导入到项目中。 然后，你还必须链接libxml2.dylib在链接二进制与图书馆项目。
一旦完成，你将不得不这样做是为了检索数据（根据您的XML源）：
NSData *xmlData = [NSData dataWithContentsOfURL:yourURL];
TBXML *tbxml = [TBXML newTBXMLWithXMLData:data error:nil];
[self getData:tbxml.rootXMLElement];
- (void) getData : (TBXMLElement *) element
{
do {
if([[TBXML elementName:element] isEqualToString:@"table"])
{
if([[TBXML elementName:element] isEqualToString:@"column"])
{
if([[TBXML attributeName:element] isEqualToString:@"nameradio"])
{
// You decide what to do here
}
}
}
if (element->firstChild) [self getData:element->firstChild];
} while(element = element->nextSibling);
}
你可能会需要更改此代码，但在这里你有所有你需要的基本的东西。
这是你如何使用的NSXMLParser：
在您的.h文件中声明：
NSMutableData *webPortFolio;
NSMutableString *soapResultsPortFolio;
NSURLConnection *conn;
//---xml parsing---
NSXMLParser *xmlParserPortFolio;
BOOL elementFoundPortFolio;
NSMutableURLRequest *req;
NSString *theXMLPortFolio;
NSString *strSoapMsg;
UIAlertView *alertView;
在您的.m文件使用下面的代码：
-(void)callURL
{
//Your logic to call URL.
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
if (conn)
{
webPortFolio = [[NSMutableData data] retain];
}
}
And to handle the response you can use following functions :
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[webPortFolio setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[webPortFolio appendData:data];
}
-(void) connection:(NSURLConnection *) connection didFailWithError:(NSError *) error
{
NSLog(@"error...................%@",[error description]);
[webPortFolio release];
[connection release];
}
-(void) connectionDidFinishLoading:(NSURLConnection *) connection
{
//Check the request and returns the response.
NSLog(@"DONE. Received Bytes: %d", [webPortFolio length]);
theXMLPortFolio = [[NSString alloc]
initWithBytes: [webPortFolio mutableBytes]
length:[webPortFolio length]
encoding:NSUTF8StringEncoding];
//---shows the XML---
NSLog(@"shows the XML %@",theXMLPortFolio);
[theXMLPortFolio release];
if(xmlParserPortFolio)
{
[xmlParserPortFolio release];
}
xmlParserPortFolio = [[NSXMLParser alloc] initWithData: webPortFolio];
[xmlParserPortFolio setDelegate: self];
[xmlParserPortFolio setShouldResolveExternalEntities:YES];
[xmlParserPortFolio parse];
[webPortFolio release];
[connection release];
}
//---when the start of an element is found---
-(void) parser:(NSXMLParser *) parser
didStartElement:(NSString *) elementName
namespaceURI:(NSString *) namespaceURI
qualifiedName:(NSString *) qName
attributes:(NSDictionary *) attributeDict
{
if( [elementName isEqualToString:@"your_tag_name"])
{
if (!soapResultsPortFolio)
{
soapResultsPortFolio = [[NSMutableString alloc] init];
}
elementFoundPortFolio = TRUE;
NSLog(@"Registration...%@",soapResultsPortFolio);
}
else if([elementName isEqualToString:@"your_tag_name"])
{
elementFoundPortFolio = TRUE;
}
else if([elementName isEqualToString:@"your_tag_name"])
{
elementFoundPortFolio = TRUE;
}
else if([elementName isEqualToString:@"your_tag_name"])
{
elementFoundPortFolio = TRUE;
}
}
-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string
{
if (elementFoundPortFolio)
{
[soapResultsPortFolio appendString: string];
}
}
- (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError
{
NSLog(@"Parser error %@ ",[parseError description]);
}
//---when the end of element is found---
-(void)parser:(NSXMLParser *)parser
didEndElement:(NSString *)elementName
namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{
if ([elementName isEqualToString:@"your_tag_name"])
{
NSLog(@"display the soap results%@",soapResultsPortFolio);
}
else if([elementName isEqualToString:@"your_tag_name"])
{
//Perform required action
}
else if([elementName isEqualToString:@"your_tag_name"])
{
//Perform required action
}
else if([elementName isEqualToString:@"your_tag_name"])
{
//Perform required action
}
[soapResultsPortFolio setString:@""];
elementFoundPortFolio = FALSE;
}
