what is the xpath syntax to grab html tag elements?

how do I print the title value for the below html file using xmlstarlet? 

thufir@doge:~/.html$ 
thufir@doge:~/.html$ xmlstarlet sel -t -v "/html/header[@name='title']" -n hello.html 

thufir@doge:~/.html$ 
thufir@doge:~/.html$ cat hello.html 
<html>
<header><title>This is title</title></header>
<body>
Hello world
</body>
</html>
thufir@doge:~/.html$

Grabbing xml might be a bit different than html? Assuming garden-variety html and not xhtml.

The reason I'm using xmlstarlet is specifically to use xpath syntax which seems rather alien.

With:

"/html/header[@name='title']"

you select an header element which has an attribute name with the value "title".

What you want is to grab a title element in an header element:

//header/title

or just use :

//title

which selects all title elements, regardless of its position in the tree.

I'd just cheat and use Chrome's Developer Tools.

Open the HTML in Chrome, open the Developer Tools, then in the Elements tab, right click and select Copy > Copy XPath.

/html/body/header/title
