This example shows a query for a-tags, that are children of a li-tag and has a class attibute with the value "link". We want to the output to be "Tag"\t"Element attributes csv"\t"value of the element ettribute href"\n for each hit

$ cat ./dummy.html | ./dominator 'li.a{class:link}' -o'tag' -o'attrib-keys' -o'attrib(href)'
a	href,id,class	#a-1-li-1-o2-1
a	href,id,class	#a-2-li-2-o2-1
a	href,id,class	#a-3-li-2-o2-1

This Example shows a query for a-tags where the href begins with "http"

a	href,id,class	https://github.com

Filter Syntax

Expression = TAG[PICK]{ATTRNAME:ATTRVALUE}
