Parsing og: tags with ColdFusion regex -

Parsing og: tags with ColdFusion regex -

if 1 wants extract/match open graph (og:) tags html, using regex (and coldfusion 9+), how 1 go doing it?

and tricky bit is has cover both possible variations of tag formation in next examples:

<meta property="og:type" content="website" /> <meta content="website" property="og:type"/>

so far got this:

<cfset tags = rematch('(og:)(.*?)>',html_content)>

it match both of links, first type has content bit returned it. , content require.

just create absolutely clear, desired output should array of og tags (they 'type,image,author,description etc.). means should flexible , not based on og:type illustration alone.

of course of study if it's possible, ideal output struct first column beingness name of tag, , sec containing value (content). can achieved post processing , not of import extracting tags themselves.

cheers, simon

so want array ['og:author','og:type', 'og:image'...]?

try using regex og:([\w]+)

that should give start. have duplicates if have 2 of same og:foo meta tags.
