Doubt in XPATH - preceding, following

[Shoba Ramachandran]

Hi,
When I try to bring all preceding-siblings for Sku element, nothing returns

<?xml version="1.0" encoding="UTF-8"?>
<Invoices>
<?hack on this?>
<Invoice ID='1000'>
<CustomerName>Jane Smith</CustomerName>
<LineItems>
<!-- here is a comment -->
<LineItem>
<Sku>134</Sku>
<Description>Dons Boxers</Description>
<Price>9.95</Price>

<LineItem>
<Sku>201</Sku>

<Price>39.95</Price>
</LineItem>
</LineItems>
</Invoice>
</Invoices>  

Shouldn't it return the following
<Description >and <Price> elements

<Description>Dons Boxers</Description>
<Price>9.95</Price>
<Description>Rice Krispy COM Object</Description>
<Price>10000.00</Price>
<Description>Red Vines</Description>
<Price>4.95</Price>
<Description>COM is LOVE T-shirt</Description>
<Price>9.95</Price>
<Description>ATL Internals</Description>
<Price>49.95</Price>
<Description>Caffeinated Beverages</Description>
<Price>0.50</Price>
<Description>Friday Pizza</Description>
<Price>0.00</Price>

If <Sku> is the first element of a <LineItem>, it won't have any preceding siblings. Maybe you should be looking for following-siblings instead?

Or you can try preceding axis instead.
BTW, no trailing 's' at preceding-sibling or following-sibling axis names. Even it seems no filling blank questions in IBM141.
