Once we have built our node tree we need some way to parse it in order to produce a pretty html formatted page.\u00a0 When I was developing this it took way to much thinking time for the number of lines of code, but there are literally 2 functions that we use, and out of them, only one is called externally (the process_nodes function).<\/p>\n
The first function is used to look for the first open sibling.\u00a0 If it finds one then it returns a pointer to that node, if not then it returns nullptr<\/p>\n
\/\/**************************************************************\/\/\r\n\/\/ ARE ALL DIRECT DECENDENTS OF THE CURRENT NODE CLOSED? \/\/\r\n\/\/**************************************************************\/\/\r\nhtml_tree *pretty_html::find_first_open_sibling(html_tree *parent) {\r\n\r\n html_tree *workNode = nullptr;\r\n\r\n for(html_tree *it : parent->childNodes) {\r\n if(it->closed() != html_tree::status::CLOSED) {\r\n workNode = it;\r\n break;\r\n }\r\n }\r\n\r\n return(workNode);\r\n}<\/pre>\n <\/p>\n
And last but not least, the process node function, this is the function that actually creates the html page.<\/p>\n
