The corresponding cell value in XML should be a "^" delimited list of following values:
1st - Link Text (or "img:image_src")
2nd - URL (optional)
3rd - target (optional, default is _blank)

Samples:
<cell>Stephen King</cell>
<cell>Stephen King^http://www.stephenking.com/</cell>
<cell>Stephen King^http://www.stephenking.com/^_self</cell>
<cell>text1,text2^http://news.sina.com.cn^ ^aaaa^http://news.21cn.com^</cell>
<cell>text1,text2^http://news.sina.com.cn^_self^aaaa^http://news.21cn.com^_blank</cell>
