get meta description tag with xpath

Question

I need the content the description and the keywords tag content. I have this code, but dont write anything. Idea?

$str = <<< EOD



        

Answer 1

In stead of including the /html/head part you could also use double slash which means that the following node can be anywhere in the code:

//meta[@name='description']

Will give the same result as:

/html/head/meta[@name='description']

Doesn't really matter much but it's less typing...
