Version 0.60 of XIA (XPath In Ada) is now available on the McKae
Technologies website at www.mckae.com/xia.html.
This version of XIA is a beta release that completes the initial
implementation of the XPath 1.0 specification. Therefore this release
has sufficient capabilities implemented that one may now consider it for
actual XML applications. Improvements and fixes to known and
to-be-discovered bugs will be incorporated into subsequent releases.
There are two significant bugs and a known limitation: The parser treats
"and", "or", "not", "div", the axis names ("child", "ancestor", etc.),
and node type names ("text", etc.) as reserved words. Meaning that if an
XML document uses such a term as an element tag, referencing it as part
of the path in an XPath expression will generate a syntax error.
Predicate expressions that specify the union, via '|', of two node-sets
will also cause a syntax error. Lastly, the id() core library function
is implemented, but inoperable, as XMLAda does not yet implement the
Get_Element_By_ID function.
The txia_test.txt file, containing a list of XPath queries that
seriously exercise the predicate filtering capabilities of XIA, has been
updated to 140 queries, and the distribution now also includes an
"expected results" file for running the txia test sequence.
As this is a beta release, reports of errors (either in operation or in
the nodes retrieved) would be appreciated. Please provide the XML
document (or readable fragment), the query that was submitted, and a
description of what was expected.
