I'm trying to write an XPath that will select certain nodes that contain a specific word. In this case the word is, "Lockwood". The correct answer is 3. Both of these paths give me 3.
count(//*[contains(./*,'Lockwood')])
count(BusinessLetter/*[contains(../*,'Lockwood')])
But when I try to output the text of each specific node
//*[contains(./*,'Lockwood')][1]
//*[contains(./*,'Lockwood')][2]
//*[contains(./*,'Lockwood')][3]
Node 1 ends up containing all the text and nodes 2 and 3 are blank.
Can some one please tell me what's happening or what I'm doing wrong.
Thanks.

This is a FAQ.
is not the equivalent to
The former selects all
//SomeExpressionnodes that are the first child of their parent.The latter selects the first (in document order) of all
//SomeExpressionnodes in the whole document.How does this apply to your problem?
This selects all elements that have at least one child whose string value contains 'Lockwood' and that are the first such child of their parent. All three elements that have a text node containing the string 'Lockwood' are the first such child of their parents, so the result is that three elements are selected.
There is no element that has a child with string value containing the string 'Lockwood' and is the second such child of its parent. No nodes are selected.
There is no element that has a child with string value containing the string 'Lockwood' and is the third such child of its parent. No nodes are selected.
Solution:
Use:
Each of these selects exactly the Nth element (N = {1,2,3}) selected by
//*[contains(./*,'Lockwood')], correspondingly:BusinesLetter,RecipientandBody.Remember:
The
[]operator has higher priority (precedence) than the//abbreviation.
