IZ97552: RESULT OF XSLT COUNT FUNCTION IS ALWAYS ONE IF THE ARGUMENT IS A NODELIST RETURNED FROM AN EXTENSION FUNCTION

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  

Local fix

• The user could switch to using the XSLT interpreter, or the user
  could write a named template that uses recursion to count the
  number of nodes in the NodeList instead of using the count
  function.
  

Problem summary

• If an extension function returns a NodeList, the result of
  applying the count function to that result is always one when
  using the XSLT compiling processor.  This affects some extension
  functions supplied by the XSLT processor, including the EXSLT
  string:tokenize and string:split extension functions.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR9 FP2
  .
  The XSLT processor uses an object called a cursor to represent a
  node set along with its position and size.  In the case of a
  NodeList returned by an extension function, the processor uses
  one cursor for each DOM Node in the NodeList, and then a "proxy"
  cursor that contains an array holding each of those individual
  cursor objects.  As the processor iterates through nodes in the
  node set represented by the proxy cursor, the proxy cursor
  positions itself at successive cursor objects in its array, and
  the proxy cursor delegates certain operations - such as
  retrieving the string value of the node, or children of the node
  - to the cursor object at which the proxy is currently
  positioned.
  The problem was that the proxy cursor delegated the count
  operation to the cursor object at which it was positioned, so it
  returned the number of nodes in the node set represented by the
  first DOM Node in the returned NodeList, which is always one in
  this case.
  The problem was resolved by changing the proxy cursor class's
  implementation of the count function to compute the sum of the
  number of nodes in each cursor in its array.
