mono/mcs/class/System.XML/System.Xml.XPath/ChangeLog

2003-11-19  Atsushi Enomoto  <[email protected]>

	* Added XPathComparer.cs
	* DefaultContext.cs : Fixed XPathFunctionId.Evaluate() to iterate base 
	  iterator correctly, and sort results.

2003-11-19  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : Imcomplete fix ;-)

2003-11-19  Atsushi Enomoto  <[email protected]>

	* DefaultContext.cs : XPathFunctions.ToNumber() should catch overflow.
	  XPathFunctionId.cs : Exposed Id expression.
	* Expression.cs : Added ExprLiteral.Value, and class ExprParens (it
	  will be used to solve evaluation precedence problem).

2003-11-09  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Fixed SlashIterator that might return nodes 1)in
	  inconsistent order, and 2)may return duplicate result nodes.

2003-11-06 Ben Maurer  <[email protected]>

	* Iterator.cs: (AxisIterator.ComparablePosition): Remove. Let
	it inherit from the base class. This made b[2] evaluated on 
	<a /><b /><c /><a /><b /><c /> return the first b node because
	in the ChildIterator it was the second node and seemed to satsify
	the predicate.

2003-11-04  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Added bool ReverseAxis property to identify whether
	  the iterator is in reverse order or not.  Added ComparablePosition
	  for correct position comparison for PredicateIterator and reverse-
	  order-axes.  Modified AncestorIterator, AncestorOrSelfIterator,
	  PrecedingIterator and PrecedingSiblingIterator to make MoveNext()
	  return their nodes in document order. This fixes bugzilla #39079.

2003-10-15  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : DescendantIterator and FollowingIterator also should
	  not MoveNext() after they reached to the end.

2003-10-13  Atsushi Enomoto  <[email protected]>

	* Iterator.cs : Fixed UnionIterator who ignores document order.
	  Fixed SlashIterator whose MoveNext() should finish at its end.

2003-09-27 Ben Maurer  <[email protected]>

	* Iterator.cs, Expression.cs, XPathNavigator.cs: In AxisIterator
	use NameTable so we dont call strcmp.

2003-09-27 Ben Maurer  <[email protected]>

	* DefaultContext.cs (translate): translate ("abc", "c", "") = "ab"
	not "abc".
	* Iterator.cs, Expression.cs: All axes are
	SimpleIterators. SimpleIterators are gaurenteed to give the same
	XPathNavigator in Current. Make AxisIterator take a
	SimpleIterator, not any old BaseIterator. Will allow us to make
	NameTable optimizations and avoid quite a few strcmp's.

2003-09-24 Ben Maurer  <[email protected]>

	* Expression.cs: make // work right, must use another slash itr.

2003-09-21 Ben Maurer  <[email protected]>

2003-09-20 Ben Maurer  <[email protected]>

	* Expression.cs: num != double.NaN does not work.

2003-09-19 Ben Maurer  <[email protected]>

	* Expression.cs: in NodeTypeTest dont throw an exception if it is
	an unknown node type (allows for better Pattern debugging).

2003-09-17 Ben Maurer  <[email protected]>

	* DefaultContext.cs: implement sum () and translate ().

2003-09-13 Ben Maurer  <[email protected]>

	* XPathNavigator.cs: Make methods where you pass in the context,
	so that we dont have to clone expressions so much.

2003-09-06 Ben Maurer  <[email protected]>

	* DefaultContext.cs, Expresssion.cs, Parser.jay: Rewrite so that
	system functions are actually expressions. Will allow for some
	nice optimizations.

2003-08-25 Ben Maurer  <[email protected]>

	* XPathNavigator.cs: "Smart" behavior in Matches. Nice 8x speed
	improvement in the method (5ms/call -> .7 ms / call) measured by
	monodoc's rendering of N:System.
	* Expression.cs: Utility methods to support above.
