I have this xml:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<root>
        <classes>
                <class name="math">
                        <lesson id="7" />
                        <lesson id="8" />
                        <lesson id="9" />
                </class>
                <class name="history">
                        <lesson id="15"/>
                        <lesson id="16"/>
                </class>
        </classes>
        <classlist>
                <lesson id="15">
                        <title>1900</title>
                </lesson >
                <lesson id="16">
                        <title>1800</title>
                </lesson >
                <lesson id="7">
                        <title>pitagoras</title>
                </lesson >

        </classlist>
</root>

I want nodelist object containing all lessons titles that belongs to the band “history”.

I need some help with the nested root of the xPath.
I know this: ("//lesson [@id = ???]/title")
What do I need to write instead of the ??? so it extract the right id numbers?

Many thanks

/classlist/lesson[@id=/classes/class[@name='history']/lesson/@id]

Sorry - it is not working.

Can you tell me the right syntax to extract the value of all the id's under the node: class?

The result should be :
7
8
9
15
16

If it's not working, then let's work out why before we ask another question. What was your input, what was your stylesheet, and what was your output. If by "not working" you mean there was an error message, then what was hte error message?

not working = nothing was returned!

my second question related to the same issue: how do I extract attribute value.
in this case I mean the output shoud be
5

and not

id="5"

Do you need any other info, or my question is not clear?
