如何使用 objective c 从 xml 信封中提取 xml 皂体？

Question

<soap:Envelope xmlns:c="http:************************" 
xmlns:soap="http://********************" 
xmlns:n1="http://**************" xmlns:n2="http:***********">
<soap:Header>
</soap:Header>
<soap:Body>

                <n2:RequestTime>2018-01-10T10:10:27</n2:RequestTime>
                <n2:MessageId>******************</n2:MessageId>
            </n2:Header>
            <n2:Body>
                <n2:LastUpdate>2017-08-06T15:34:00</n2:LastUpdate>
            </n2:Body>
        </n1:request>
    </n1:GetDeviceConfiguration>
</soap:Body>

从这个 xml 我想使用 objective C.

提取 soap:Body

Answer 1

您可以使用 XMLParser 提取 soap Body。

首先将你的xml转换成NSData，调用解析器解析。

    //converting into NSData
    NSData* data = [theXML dataUsingEncoding:NSUTF8StringEncoding];

    //initiate  NSXMLParser with this data
    NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data];

    //setting delegate
    parser.delegate = self;

    //call the method to parse
    BOOL result = parser.parse;

    parser.shouldResolveExternalEntities = true;

现在，您需要在 class 中实现 NSXMLParser 委托。

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary<NSString *,NSString *> *)attributeDict {
currentElement = elementName;
NSLog(@"CurrentElementl: [%@]",elementName);

}

-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
NSLog(@"foundCharacters: [%@]",string);

}

您将在 xml 的键下找到值。

不要忘记将 NSXMLParserDelegate 添加到您的 class 界面中。
