调用传参

 NSString *bodyString =  [NSString stringWithFormat:
                                 @"<GetInventoryList xmlns=\"http://WmsService/\">\
                                 <materialRequisitionNum>%@</materialRequisitionNum>\
                                 </GetInventoryList>",self.beforeSelectedMaterialNum];
        
        [LSHttpTool SOAPData:PiKingKB_getSLDetail soapBody:bodyString success:^(id responseObject) {
            NSLog(@"%@", responseObject);
        } failure:^(NSError *error) {
            NSLog(@"%@", error);
        }];

通过正则表达式取出XML节点数据，正则表达式:(?<=GetInventoryListResult\>).*(?=</GetInventoryListResult>)

NSString *result = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        // 利用正则表达式取出<GetInventoryListResult></GetInventoryListResult>之间的字符串
        NSRegularExpression *regular = [[NSRegularExpression alloc] initWithPattern:@"(?<=GetInventoryListResult\\>).*(?=</GetInventoryListResult>)" options:NSRegularExpressionCaseInsensitive error:nil];
        NSDictionary *dict = [NSDictionary dictionary];
        for (NSTextCheckingResult *checkingResult in [regular matchesInString:result options:0 range:NSMakeRange(0, result.length)]) {
            // 得到字典
            dict = [NSJSONSerialization JSONObjectWithData:[[result substringWithRange:checkingResult.range] dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableLeaves error:nil];
        }
