本人使用正则表达式代码，解析响应output，意图获得周边的CMCC热点

代码如下：

有龟背山热点，但是中国移动南方基地的距离有问题

表示很奇怪，问题应该出在

                        MatchCollection hotspotMatches = Regex.Matches(output,RegexOptions.Singleline);

觉得代码没有错误，猜测：

wp项目中的正则表达式不够给力，（尤其是对于collection的处理）导致了这一问题的产生。

于是，尝试着不直接让MatchCollection一口吃成一个胖子

而是两步走，

获得具体的<hotpointInfo>...</hotpointInfo>节点
针对每一个node进行针对性的处理

心想，这样，总算是细嚼慢咽了吧

改进代码如下：

实验发现，有效解决了问题，我称之为“龟背山问题”

总结经验，

不要盲目相信MatchCollection的能力，尤其针对复杂的正则表达式

将复杂的，大的问题拆分成小问题，相信计算机，对于处理针对化问题的能力，还是值得信赖的！

解决问题之，wp项目中使用MatchCollection正则表达式匹配出错

猜你在找的正则表达式相关文章
