How to fetch META tag value of HTML inside the IPL file.

sniv

Hello,
Will anybody help me out for How to fetch META tag value of HTML inside the IPL file.

As I have one Meta tag, I need that meta tag value in IPL ( IPL containing the Data deploy command)

Is this what you are talking about ?

You have an IPL that runs DataDeploy. Before DD runs, the IPL opens and reads the HTML, parses out the HTML tags, and makes them extended attributes. Then DD runs and deploys the EAs ?

Yes, nipper. I needs to parses out HTML tag and fetch the value of HTML Meta tag in the IPL file.

Is it possible?
As I know, we can parse XML file and fetch value from xml to IPL.

e.g. -
use TeamSite::XMLparser;
my $parser = TeamSite::XMLparser->new();
my $rootnode = $parser->parse($xml);
my $TITLE=$rootnode->value('TITLE');

But is any way for HTML parsing? I wanted only one Meta tag value of HTML in IPL.

and thanks for your quick reply.......

You can use regexes to easily do that. For example, something like the following is a quick and dirty way to
obtain "content" attribute of the "http-equiv" HTML Meta.

$html =~ m/<meta\s+http-equiv.*?content=["'](.+?)["']/i;
# $1 contains Value of the content attribute of http-equiv HTML Meta

In other words, learn to love regex.

Actually I have following Meta tag in html.....

meta http-equiv="PATH" content= iw_value name='dcr.title'

Now i wanted to catch value of this meta tag in my Workflow ipl/cfg.

So how can i catch this value? is it like -

"$html =~ m/meta\s+http-equiv.*?content=["'](.+?)["']/i;"

I have tried with it but it is not working for me, Value of $html is getting blank.

Any idea what's wrong there?

Did you mean "Value of $1 is getting blank"?
Post an exact value of $html variable right before matching, I'll take a look

Here Attaching the files...

HTML file which contains META tag value - html.txt

IPL file in which html value needs to catch- IPL.txt

In IPL.txt there is block named - HTML Parsing ....where the html META tag value fetched.

Whatever you used to create the PERL script is embedding text formatting codes within the file - this is a big "no-no" - I'd be surprised if the script ran at all as-is.

Beyond that - you're using a regex on $html - but $html never appears to be set to the contents of your HTML code - so there's nothing to process in the regex.

Basically - what you posted is garbage (sorry, but that's what it is) - I suggest you use a different editor application and spend a bit more time with Perl books ...

also, try to make your HTML clean. in one line you managed to use single and double quotes, and no quotes at all.

AH, yes, consistency, it is a beautiful thing
