how to export ''Keywords" , "Description" tag in HTML file using LIbXml?

For keywords, assuming you want the text in the content attribute:

Code:

/html/head/meta[@name="keywords"]/@content

For description:

Code:

/html/head/meta[@name="description"]/@content

Keep in mind that the html you are trying to parse/query needs to be xml compliant. Also be aware that xml is case sensitive, so if the html document uses a different case (i.e. <META/> or <meta name="KEYWORDS"/>, etc). then this xpath expression wont work.

You may be better off using DOM or regular expressions, depending on what you want

 

Let me reiterate. Go through the XPath tutorial here. http://www.w3schools.com/xpath/. You can't just stab in the dark and expect to get very far.

 

So this example of the tutorial wasn't illuminating?

You didn't go "Well that's pretty much what I want except I want meta elements that have an attribute named name with a value of description. The forumula seems to be //element[@attribute='value'], perhaps I'll give //meta[@name='description'] a go'. You really didn't run that thought?! Oh, wait, of course you didn't. I seem to have forgotten whose post it is I'm reply to.
