HTML-XML-utils由一套小型C程序（过滤器）组成

2002-10-29  Bert Bos  <[e-mail]>

	* xselect.c: now supports case-insensitive matching

	* xref.c: when finding a match, now ignores all characters except
	letters, digits and dashes.

	* uncdata.c: Fixed bug: forgot to print "<!" when starting a
	comment.

	* toc.1: Added option -t

	* Released version 2.4

	* dtd.hash: added table as possible parent for tr. It's not
	correct, but it avoids an incorrect correction with tr inside a
	nested table: it closed the nested table and considered the tr to
	be part of the outer table. A better solution is needed...

2002-02-20  Bert Bos  <[e-mail]>

	* uncdata.c: new program: removes CDATA sections from XML files.

2002-02-18  Bert Bos  <[e-mail]>

	* xselect.c: Added options -s (separator) and -i
	(case-insensitive). Added some documentation.

2002-02-14  Bert Bos  <[e-mail]>

	* selector.c: fixed bug in recognition of attribute selectors:
	pointer was incremented before the character was stored, instead
	of the reverse.

2002-02-05  Bert Bos  <[e-mail]>

	* Released version 2.2.

	* cite.c: Now accepts a -m option to flag references. This allows
	to find differently flagged references in different passes.

	* multitoc.c: Fixed two bugs: a missing ! before strncmp and
	missing printf(">"), which caused headings with child elements to
	be copied incorrectly.

2001-09-25  Bert Bos  <[e-mail]>

	* index.c: Fixed bug: no longer tries to index empty elements,
	such as "<dfn></dfn>"

2001-08-01  Bert Bos  <[e-mail]>

	* selector.c: Bug fixed: some occurrences of START_EQ were renamed
	to EQ, but not all.

	* select.c: renamed to xselect.c, because select is a built-in
	command of certain shells.

2001-07-17  Bert Bos  <[e-mail]>

	* unent.hash: fixed bug that copied a whole line instead of a
	single unexpanded entity. Added option -b ("built-in") to leave
	standard entities (amp, gt, lt, quot) untocuhed.

	* Released version 2.0

	* normalize.c: Added option -d to omit the doctype from the
	output.

2001-07-16  Bert Bos  <[e-mail]>

	* selector.c: Fixed bug in parsing of "[name]"; fixed missing
	case in attribs_to_string()

	* select.c: Now implements :lang and :nth...(an+b)

2001-07-10  Bert Bos  <[e-mail]>

	* Released version 1.8

	* mkbib.c: fixed bug in read_entries(). On Linux, calling
	hsearch() with an action of ENTER replaces any existing data
	with new data, if it is different, On Solaris the existing record
	is kept. The routine now puts the data in the existing record.

2001-07-09  Bert Bos  <[e-mail]>

	* Released version 1.7

	* selector.c: Added (types and a parser for CSS selector)

	* select.c: Added (implementation of CSS selectors)

2001-05-23  Bert Bos  <[e-mail]>

	* Released version 1.6

2001-05-21  Bert Bos  <[e-mail]>

	* toc.c: In expand(), if keep-anchors is false, IDs are now not
	copied either.

2001-04-19  Bert Bos  <[e-mail]>

	* textwrap.c: Fixed bug when space fell exactly at end of line.
	But logic still is not perfect, since it creates spaces (indents)
	on empty lines.

2001-03-22  Bert Bos  <[e-mail]>

	* toc.c: </li> was not printed, even if xml was True

2001-02-04  Bert Bos  <[e-mail]>

	* printlinks: added. 

2000-09-14  Bert Bos  <[e-mail]>

	* normalize.c: Fixed bug that caused text not to be preformatted
 	inside an element nested inside a PRE.

	* textwrap.c: Fixed bug that caused lines not to be broken at all
 	if there was no break point before the target length.

2000-09-04  Bert Bos  <[e-mail]>

	* xref.c: now skips quotes when comparing terms

2000-08-29  Bert Bos  <[e-mail]>

	* Released version 1.3

2000-08-26  Bert Bos  <[e-mail]>

	* index.c: termcmp() now correctly compares keys that end with
 	punctuation.

	* normalize.1: now describes the -e (add endtags) option.

	* xref.c: now uses title attribute in instances as well

2000-08-21  Bert Bos  <[e-mail]>

	* Released version 1.2

	* All occurrences of "DOCTYPE" are now in uppercase.

2000-08-20  Bert Bos  <[e-mail]>

	* tree.c: Now checks if there is a parent open before popping
	elements from the stack.

	* textwrap.c: Now flushes at \n or \r in preformatted, because
	long preformatted elements could too easily overflow the buffer.

	* html.y: Added some const's to formal parameters

	* genid.c: minlen now works even if there are child elements; no
 	longer skips '-' and '.' when it generates an ID; no longer
	generates zero-length IDs.

	* cexport.c: Now recognizes quoted file names after "#line"

	* class.c: Put contains() and has_class() in new file

	* Makefile.am: Added addid and extract

Version 1.1 (2 August 2000)

    Better (?) heuristic for closing and generating elements in
    html_push() in tree.c. It no longer closes and re-opens the <html> 
    element in case both </head> and <body> are missing.

    Different path for bash (/usr/local/bin/bash instead of
    /usr/local/gnu/bin/bash) in cite-mkbib.

    cite-mkbib was missing from the tar file.

    Program incl changed. It now looks for <!--include "file"-->.
    Because of that, a callback endincl() was added in html.y

    Some programs now interpret argument "-" as meaning "read from
    standard input."

    Fixed bug in toc: it didn't correctly guard against re-use of IDs, 
    since it stored a random string rather than an ID in the binary
    tree.

    Added some handy functions to types.c: stapp(), chomp(), min(),
    max().
