当我解析以下XML并将其存储在HashMap中时,消息会在(')此符号后被剪切。
实施例。消息:“嘿阿玛!怎么了?”它像这样切割。
最终输出是:message =“s up?”
那么如何解决这个问题?
支持XML DATA的HashMap:
public static HashMap<String,String> message_map1 = new HashMap<String,String>();
public static HashMap<String,String> message_map2 = new HashMap<String,String>();
public static HashMap<String,String> message_map3 = new HashMap<String,String>();
XML:
<statuses type="array">
<status>
<messageinfo>
<messageid>485</messageid>
<userid>58</userid>
**<message>Hey amar! What's up?</message>**
</messageinfo>
<messageinfo>
<messageid>486</messageid>
<userid>58</userid>
**<message>Hey What's up?</message>**
</messageinfo>
<messageinfo>
<messageid>485</messageid>
<userid>58</userid>
**<message>What's up?</message>**
</messageinfo>
</status>
</statuses>

问题: 日志: 07-04 13:38:37.924:VERBOSE / message =(3577):嘿阿玛!什么 07-04 13:38:37.934:VERBOSE / message =(3577):' 07-04 13:38:37.934:VERBOSE / message =(3577):s up?
答案 0 :(得分:2)
解析器可以多次调用characters
方法,在每次调用时只提供给定标记内的部分字符。
此代码不允许发生这种情况。
您需要做的是在startElement
方法中设置字符串缓冲区,在characters
中将字符收集到其中,并在endElement
方法中提取字符串结果。

Don Roby回答说。
获取一个String变量并在endElement()方法中添加你的in_message变量为false的地图。
例如,这样做......
String str = "";
//在characters()方法中 否则if(in_message) { str + = chars; } //在endElement()方法
中else if(localName.equalsIgnoreCase(“message”)) { in_message = false; map.put(“message”,str); Log.i(“map”+ i,“message =”+ str); str =“”; } `
