Where does it say which of the axis identifiers are and are not legal match patterns? Production [5] states AxisIdentifier ::= 'from-ancestors' | 'from-ancestors-or-self' | 'from-attributes' | 'from-children' | 'from-descendants' | 'from-descendants-or-self' | 'from-following' | 'from-following-siblings' | 'from-parent' | 'from-preceding' | 'from-preceding-siblings' | 'from-self' Section 6.4 states that "A pattern must match the grammar for Pattern. A Pattern is set of location path patterns separated by |. A location path pattern is a location path none of the steps of which use either AxisIdentifiers or . or ... " Furthermore none of the examples of patterns include axis identifiers. Following the grammar out I don't see any way to get any AxisIdentifier in as part of a pattern. What am I missing? Or is the draft spec incorrect? +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@xxxxxxxxxxxxxxx | Writer/Programmer | +-----------------------+------------------------+-------------------+ | Java I/O (O'Reilly & Associates, 1999) | | http://metalab.unc.edu/javafaq/books/javaio/ | | http://www.amazon.com/exec/obidos/ISBN=1565924851/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://metalab.unc.edu/javafaq/ | | Read Cafe con Leche for XML News: http://metalab.unc.edu/xml/ | +----------------------------------+---------------------------------+ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
