Error in chapter on web applications #26

Closed cmsmcq closed 3 years ago

cmsmcq commented 3 years ago

The chapter on web applications [1] says, among other things

In Scryer Prolog, library(xpath) allows us to access HTML elements by XPath specifications in a straight-forward way.

But the example shown (//li(text)) is not an XPath expression. It would be more accurate to describe the library as is done in the SWI Prolog documentation [2], as using "descriptions inspired by the XPath language". Saying the expressions are XPath, when it is obvious at a glance that they are not, gives a bad impression, at least to some readers.

This is a valid criticism. I have installed 00b4302f37cc53ba1b76537ef940ef9ae15c5c31 to address it, could you please take a look?

Thank you a lot for reporting this!
