废话不说,直接进入正题。
KissXML的配置和使用,请参考:http://blog.csdn.net/ryantang03/article/details/7926268
直接上解析代码:
+(NSMutableArray *)xmlPaserWithData:(NSData *)xmlData andElements:(NSMutableArray *)elements andNode:(NSString *)node
{
/*
xmlData : xml文件转换为 NSData
elements : 节点中的所有元素
node : 需要解析的节点
*/
NSMutableArray *xmlArray=[[NSMutableArray alloc]init];
NSMutableDictionary *xmlDictionary;
//文档开始(KissXML是基于DOM的解析方式)
DDXMLDocument *xmlDoc = [[DDXMLDocument alloc] initWithData:xmlData options:0 error:nil];
NSArray *nodes=[xmlDoc nodesForXPath:[NSString stringWithFormat:@"//%@",node] error:nil];
for (DDXMLElement *nod in nodes) {
xmlDictionary=[[NSMutableDictionary alloc]init];
for (int i=0; i<[elements count]; i++) {
DDXMLElement *element=[nod elementForName:[NSString stringWithFormat:@"%@",[elements objectAtIndex:i]]];
NSLog(@"elements is %@ and string is %@",element,[element stringValue]);
if ([xmlDictionary valueForKey:[element stringValue]]!=nil) {
[xmlDictionary removeObjectForKey:[element stringValue]];
}
[xmlDictionary setValue:[element stringValue] forKey:[NSString stringWithFormat:@"%@",[elements objectAtIndex:i]]];
}
NSLog(@"xmlDictionary is %@",xmlDictionary);
[xmlArray addObject:xmlDictionary];
NSLog(@"xmlarray is %@",xmlArray);
}
return xmlArray;
}
在以上代码,xmlData 是xml文件或流生成的NSData类型数据,elements数组包含需要解析的子节点名称,node为当前需要解析的父节点。
我们新建一个类,将上面解析方法写入,新建类名称为XMLParser .
如下XML :
<retValue>
<status>
<statusCode>1</statusCode>
</status>
<records>
<record>
<moduleName>PurchasePlan</moduleName>
<newMessage>2</newMessage>
</record>
<record>
<moduleName>PurchaseOrder</moduleName>
<newMessage>0</newMessage>
</record>
<record>
<moduleName>Complaint</moduleName>
<newMessage>3</newMessage>
</record>
<record>
<moduleName>RealityCheck</moduleName>
<newMessage>5</newMessage>
</record>
<record>
<moduleName>Attention</moduleName>
<newMessage>6</newMessage>
</record>
</records>
</retValue>
//moduleName和newMessage为我们需要获取的子节点
NSMutableArray *elements=[NSMutableArray arrayWithObjects:@"moduleName",@"newMessage", nil];
//record为 moduleName和newMessage父节点
NSMutableArray *moduleCount=[XMLParser xmlPaserWithData:xmlData andElements:elements andNode:@"record"];
调用解析方法后,获得解析后的数组moduleCount ,moduleCount数组内容如下:
(
{
moduleName = PurchasePlan;
newMessage = 2;
},
{
moduleName = PurchaseOrder;
newMessage = 0;
},
{
moduleName = Complaint;
newMessage = 3;
},
{
moduleName = RealityCheck;
newMessage = 5;
},
{
moduleName = Attention;
newMessage = 6;
}
)
ok ,用的时候,直接调用数组使用即可。
