一个轻量级的 Objective-C-HMTL-Parser 解析库，这里主要是希望 HTML 解析出想要的标签字段。
题外：如果是要将 HTML 解析成富文本展示，推荐 DTCoreText。
添加到 framework 或 app 在 Build Setting 的 Header Search Paths 添加 $(SDKROOT)/usr/include/libxml2。
如果是添加到 podspec 则添加，则：
s.library = 'xml2'
s.xcconfig = { 'HEADER_SEARCH_PATHS' => '$(SDKROOT)/usr/include/libxml2', 'OTHER_LDFLAGS' => '-lxml2' }
解决 libxml2 中文乱码
