问题描述
我正在研究有关解析google weather api的示例iPhone教程，该api似乎已不存在，因此我已经找到了一个替代方案.本教程使用libxml2和xpath查询来解析xml文件.我成功地解析了大多数数据.我的问题是天气符号的图标URL包含在CDATA部分中:
Im working through an example iphone tutorial on parsing the google weather api, The api seems to no longer exist so I have sourced an alternative. The tutorial uses libxml2 and xpath query to parse the xml file. I am succesfully parsing most of the data. The problem I have is that the icons url for the weather symbols are enclosed in CDATA sections:
<weatherIconUrl><![CDATA[http://www.worldweatheronline.com/images/wsymbols01_png_64/wsymbol_0010_heavy_rain_showers.png]]></weatherIconUrl>
我了解xpath无法读取CDATA中包含的项目.反正从标记中提取此数据吗?
I understand that xpath cannot read items enclosed in CDATA . Is anyway of pulling this data from within the tags?
推荐答案
使用parser:foundCDATA:
- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock
解析CDATA.
