我想從根節點創建兩個循環，以獲取標題和鏈接，但coudnt弄清楚如何做到這一點。任何人都可以幫忙嗎？

CXMLElement *element; 
NSArray *titleItems = [[NSArray alloc] initWithArray:[element nodesForXPath:@"//category" error:nil]]; 
for(CXMLElement *item in titleItems){ 
NSString *title = [[item selectSingleNode:@"title"] stringValue]; 

}

注：類節點應該重複.....

節點命名爲，等等，所以我不能用你的XPath –

CXMLNode *節點;對於（i = 0; i <10; i ++）{NSString * xpath = [NSString stringWithFormat：@「// category％d/title」，i]; NSArray * title = [[nodes nodesForXPath：xpath] stringValue]; } – Cintu

如果你可以改變你的XML文件，並讓所有的類別標籤一樣。你可以把所有...而不是...和...

所以這將是很容易解析。你只需要做類別類，如果你有正確的XML解析代碼，所有的標籤都會被自動解析。

我不能改變XML。你能幫助解析當前的XML嗎？ –

你可以使用這個庫來解析你的xml。 http://allseeing-i.com/ASIHTTPRequest/How-to-use – Deeps

CXMLNode *node; 
for(i=0; i<10 ; i++){ 
    NSString *xpath = [NSString stringWithFormat:@"//category%d/title", i]; 
    NSArray *title = [[node nodesForXPath:xpath] stringValue]; 
}

使用上面的代碼..

下面的代碼給你一個字典，其中鍵是標題和數據的鏈接。當然，如果你的XML文檔「很大」，這不是最好的辦法。

CXMLDocument *doc = [[[CXMLDocument alloc] initWithXMLString:theXML options:0 error:nil] autorelease]; 
NSArray *categories = nil; 
NSMutableDictionary* results = nil; 
categories = [doc nodesForXPath:@"/categories/*[starts-with(name(), 'category')]" error:nil]; 
if (categories != nil && [categories count] > 0) 
{ 
     results = [NSMutableDictionary dictionaryWithCapacity:[categories count]]; 
     for (CXMLElement *category in categories) 
     { 
       NSArray* titles = [category elementsForName:@"title"]; 
       if ([titles count] >0) 
       { 
        NSArray* links = [category elementsForName:@"link"]; 
        [result setObject:([links count]>0?[[links objectAtIndex:0] stringValue]:nil; 
          forKey:[[titles objectAtIndex:0] stringValue]]; 
       } 
     } 
}
