rss发生 xmlParseEntityRef: no name 错误

An XML parser returns the error “xmlParseEntityRef: no name” 

There is a stray ‘&’ (ampersand character) somewhere in the XML text eg. some text & some more text 

方法 1: Remove the ampersand. 
方法 2: Encode the ampersand (that is replace the ‘&’ character with ‘&’ ). Remember to Decode when reading the XML text. 
方法 3: Use CDATA sections (text inside a CDATA section will be ignored by the parser.) eg. <![CDATA[some text & some more text]]> 

笔记: ‘&’ ‘<' '>‘ will all give problems if not handled correctly.
