Extract Meta Tags....

[ClarkKent101]

Hi Everyone,

I would just like to know - is it possible to extract the Meta Tag keywords/page title off of a webpage using Coldfusion?

I've been scouting the web looking for an example similar to what I want done to see if I could get pointed in the right direction but I've had no luck and so am beginning to wonder if it's even possible to do this. I know it's possible in PHP which has left me hoping it can be done in Coldfusion too .

Thanks for your time,

- CK

there is no function that i can think of off the tp of my head, but it can be done.

You'd have to use cfhttp and then some string finding to do it. Something like this:

<cfhttp url="url you want to go to" method="get" />

<cfset metaKeyword = '<meta name="Keywords"'>
<cfset metaKeywordStart = FindNoCase(cfhttp.filecontent, metaKeyword)>

<cfset metaKeywordEnd = FindNoCase(cfhttp.filecontent, '>', metaKeywordStart)>

<cfoutput>
#Mid(cfhttp.filecontent, metaKeywordStart, (metakeywordEnd-metaKeywordStart))#
</cfoutput>

Something like that

Hope this helps!

Hi Tony,

Thanks a bunch! Perfect kickstart - only thing I changed in your code above is the parameter order in the FindNoCase() function...

<cfhttp url="url you want to go to" method="get" />

<cfset metaKeyword = '<meta name="Keywords"'>
<cfset metaKeywordStart = FindNoCase(metaKeyword, cfhttp.filecontent)>

<cfset metaKeywordEnd = FindNoCase('>', cfhttp.filecontent, metaKeywordStart)>

<cfoutput>
#Mid(cfhttp.filecontent, metaKeywordStart, (metakeywordEnd-metaKeywordStart))#
</cfoutput>

Thanks again,
