[Current node]
(
)
The English version is available.
Test of using XPath expressions.
Here is the child . operator:
Here is the parent .. operator:
Here is the /sibling operator applied to isbn:
../nodeName - here ../isbn
Here is the wildcard operator * :
Recall the .. means select the node's parent and * means then show whatever you got there!
../*
The double slash // selects all of the descendants of the root node.:
//book
Skip the current note to go from root to element:
/root/[elements], e.g., /books/book/editors/editor
To test whether an element even has an attribute:
use [ then the expression and then ] e.g., [@language="eng"]
Or even to test the node location, e.g., [position() = last()]
Position test (last)
Test of being last English node
This is a test. The cost for the book is $.
Note! Because we're in a for-each test only for the node "name", to
see the price (in the cost node) we have to go up to the grandparent and then
come back down the node tree 'til we find cost
Great Price! Buy it
Kind of expensive; get the paperback.
Notice that if you read the .xsl file, you'll see the value-of statement here.
Notice how the select points to . [that's the current node] in otherwords we see the words
"welcome" - odd isn't it?!
