XSLT and XPath

[Mariusz Sieraczkiewicz]

I have three variables: a, b, c.

And sample XML tree :

<parents>
<parent>
<child1>ssfd</child1>
<child2>dfoi</child2>
<child3>dijf</child3>
</parent>
............
<parent>
<child1>s34d</child1>
<child2>d44i</child2>
<child3>d342</child3>
</parent>
<parents>

how to write XPath expression that
returns the value of the child named c,
having sibling named a with value of b.
The start point is the 'parents' element.

Sample a = 'child1', b = 's34d', c='child3'

returns d342.

Regards.

Use:

/parents/parent/*
[name = $c
and
../*[name = $a] = $b
]

Thx, could you suggest some reading about such complex expressions?

This is really a very simple expression.

I'd recommend getting and playing with the XPath Visualizer:

Good books, which also cover XPath are:

1. "XSLT Programmer's Reference" by Michael Kay

2. "Beginning XSLT" by Jeni Tennison
