using xpath, how do you select the n-th option ?
<select>
<option></option>
<option></option>
</select>
/html/body/select/option[?]开发者_运维知识库
what you have is correct:
for the 2nd option, use:
/html/body/select/option[2]
or
/html/body/select/option[position()=2]
See http://www.w3.org/TR/xpath#location-paths
Edit
Note that the above assumes you have a structure like:
<html>
<body>
<select>
<option></option>
<option></option>
</select>
</body>
</html>
If your select is inside of a parent other than body, then you either want to use something like:
/html/body/div[@class='header']/select/option[2]
or
//select/option[2]
Of course, since your select probably has a name attribute, you could use that, e.g.
//select[@name='myselect']/option[2]
