Other Aliasns_hrefs, ns_quotehtml
ns_hrefs returns a list of all the URLs that the html has <A> links to. There is currently no provision for normalizing any relative URL with a specified <BASE> URL. Also, for a URL to be returned the HREF attribute must come before any other attributes (such as TITLE, STYLE, etc.) within the opening <A> tag.
ns_quotehtml substitutes all instances of "<", ">", and "&" within html with their respective HTML entities ("<", ">", and "&" respectively). This command is useful if you want to include html in another page as plain text.
ns_striphtml returns a new string that is html with all the HTML tags removed. HTML entities are left untouched.
