I disabled libiconv wich was LGPL so now everything should be MIT.
The project is at github, simply run xpathTest.pb, it's a very simple xpath test, just a proof of concept:
https://github.com/omegakode/PBLibXML2
LibXML2 is crossplatform Win64, Linux and MacOS supported.
Linux:
sudo apt-get install libxml2-dev
MacOS:
Install MacPorts
https://www.macports.org/
And:
sudo port install libxml2
LibXML2 source if you want to compile it by yourself:
https://github.com/GNOME/libxml2
LibXML2 manual:
https://gnome.pages.gitlab.gnome.org/li ... index.html
XPath 1.0
https://www.w3.org/TR/1999/REC-xpath-19991116/
The xpathTest.pb example:
Code: Select all
;xpathTest.pb
