Error description in readme.md

In the Extended syntax supported section:
https://github.com/code4craft/xsoup/blob/master/README.md

The expression of start with function and regex function are conflicted:
attribute value start with: [@key~=value] yes
attribute value match regex: [@key~=value] yes

According to Jsoup selector syntax:
http://jsoup.org/cookbook/extracting-data/selector-syntax
In the selector overview of Jsoup:
[attr^=value], [attr$=value], [attr_=value]: elements with attributes that start with, end with, or contain the value, e.g. [href_=/path/]

Hence I think the expression of start with in Xsoup should be that:
attribute value start with: [@key^=value]
