./div/b
a relative path
//table[parent::div[@class="pad"] and not(@id)]//a

XPath functions
===============
Conversion:
boolean([object])
string([object])
number([object])
Math:
ceiling(number)
floor(number)
round(decimal)
sum(node-set)
Logic:
true()
false()
not(expr)
Node:
lang(string)
name([node-set])
namespace-uri([node-set])
text()
Context:
count(node-set)
function-available(name)
last()
position()
String:
contains(haystack-string needle-string)
concat(tring1 string2[stringn]*)
normalize-space(string)
starts-with(haystack needle)
string-length([string])
substring(string start[length])
substring-after(haystack needle)
substring-before(haystack needle)
translate(string abc XYZ)
