如何使用触摸XML解析此文件?在iPhone中使用触摸xml解析文件
,这是代码我使用:
-(void) grabRSSFeed:(NSString *)blogAddress {
// Initialize the blogEntries MutableArray that we declared in the header
blogEntries = [[NSMutableArray alloc] init];
// Convert the supplied URL string into a usable URL object
NSURL *url = [NSURL URLWithString: blogAddress];
// Create a new rssParser object based on the TouchXML "CXMLDocument" class, this is the
// object that actually grabs and processes the RSS data
CXMLDocument *rssParser = [[[CXMLDocument alloc] initWithContentsOfURL:url options:0 error:nil] autorelease];
// Create a new Array object to be used with the looping of the results from the rssParser
NSArray *resultNodes = NULL;
// Set the resultNodes Array to contain an object for every instance of an node in our RSS feed
resultNodes = [rssParser nodesForXPath:@"//Bar" error:nil];
// Loop through the resultNodes to access each items actual data
for (CXMLElement *resultElement in resultNodes) {
// Create a temporary MutableDictionary to store the items fields in, which will eventually end up in blogEntries
NSMutableDictionary *blogItem = [[NSMutableDictionary alloc] init];
// Create a counter variable as type "int"
int counter;
// Loop through the children of the current node
for(counter = 0; counter < [resultElement childCount]; counter++) {
// Add each field to the blogItem Dictionary with the node name as key and node value as the value
[blogItem setObject:[[resultElement childAtIndex:counter] stringValue] forKey:[[resultElement childAtIndex:counter] name]];
}
// Add the blogItem to the global blogEntries Array so that the view can access it.
[blogEntries addObject:[blogItem copy]];
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [blogEntries count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
// Set up the cell
int blogEntryIndex = [indexPath indexAtPosition: [indexPath length] -1];
cell.textLabel.text=[[blogEntries objectAtIndex: blogEntryIndex] objectForKey: @"BarId"];
return cell;
}
任何一个可以帮我如何解析呢?
答
CXMLDocument *rssParser = [[[CXMLDocument alloc] initWithContentsOfURL:url options:0 error:nil]autorelease];
NSArray *items = [rssParser nodesForXPath:@"//Bar" error:nil];
for (CXMLElement *resultElement in items) {
Data *objData = [[Data alloc] init];
NSArray *BarIds = [resultElement elementsForName:@"BarId"];
for (CXMLElement *id in BarIds) {
objData.id = id.stringValue;
break;
}
NSArray *Types = [resultElement elementsForName:@"Type"];
for (CXMLElement *Type in Types) {
objData.type = Type.stringValue;
break;
}
NSArray *Locations = [resultElement elementsForName:@"Location"];
for (CXMLElement *Location in Locations) {
objData.type = Location.stringValue;
break;
}...
使用此您可以获取使用TuochXML的XML文件中的数据,比objData保存为Array对象 ...,并用它在表来表示。
可能对您有用
