How to write an XPath query to match two attributes?

Question

//div[@id='..' and @class='...]

should do the trick. That's selecting the div operators that have both attributes of the required value.

It's worth using one of the online XPath testbeds to try stuff out.

or //div[@id='id-74385'][@class='guest clearfix']

Adding to Brian Agnew's answer.

You can also do //div[@id='..' or @class='...] and you can have parenthesized expressions inside //div[@id='..' and (@class='a' or @class='b')].

Sample XML:

<X>
<Y ATTRIB1=attrib1_value ATTRIB2=attrib2_value/>
</X>

string xPath="/" + X + "/" + Y +
"[@" + ATTRIB1 + "='" + attrib1_value + "']" +
"[@" + ATTRIB2 + "='" + attrib2_value + "']"
