Das eez kaput! Sometime around 2002 I spaced the entire database table that mapped individual entries to categories. Such is life. What follows is a random sampling of entries that were associated with the category. Over time, the entries will be updated and then it will be even more confusing. Wander around, though, it's still a fun way to find stuff.
Date: Sun, 8 Sep 2002 15:35:43 -0400 (EDT) From: Aaron Straup Cope To: Karl Dubost Cc: Steph Subject: Glossaries: XPath, SAX and benchmarks So, I sat down and did some tests this morning per our conversation about glossaries and XBEL and XPath. It's a bit depressing given the nature of the XPath query you need to pull stuff out of an XBEL document : "/xbel//bookmark[title=\"$keyword\"]/\@href" Since the <bookmark> element can be either next to the root <xbel> element or contained in an arbitrary number of nested <folder> elements, there isn't much too do except sniff around every node until you find what you're looking for. Which takes a long time. Longer than you'd normally want anyway... On the other hand, if you just use a plain old SAX widget to find the keyword, it takes roughly 1/4 to 1/5 of the time to do a lookup. Below are benchmarks for 100 iterations of a subroutine that does 5 keyword lookups against an XBEL file. Note that the XPath query doesn't even instantiate a new object; the same object is shared across all 500 calls to 'find'. The SAX query on the other hand, instantiates a new filter and a new parser for each lookup. Obviously, some clever caching of lookups would speed things up as well. **** 101 ->./debug.xbel Benchmark: timing 100 iterations of xpathquery... bquery: 765 wallclock secs (645.73 usr + 13.66 sys = 659.38 CPU) @ 0.15/s (n=100) 101 ->./debug.xbel Benchmark: timing 100 iterations of saxquery_pureperl... saxquery_pureperl: 171 wallclock secs (148.23 usr + 0.62 sys = 148.86 CPU) @ 0.67/s (n=100) 102 ->./debug.xbel Benchmark: timing 100 iterations of saxquery_expat... saxquery_expat: 171 wallclock secs (148.17 usr + 0.20 sys = 148.38 CPU) @ 0.67/s (n=100) **** package Foo; use base qw (XML::SAX::Base); sub keyword { my $self = shift; $self->{'__keyword'} = $_[0]; } sub link { my $self = shift; return $self->{'__link'}; } sub start_element { my $self = shift; my $data = shift; return if ($self->{'__match'}); if ((! $self->{'__bookmark'}) && ($data->{Name} eq "bookmark")) { $self->{'__bookmark'} = 1; } return if (! $self->{'__bookmark'}); if ($data->{Name} eq "bookmark") { $self->{'__link'} = $data->{Attributes}->{'{}href'}->{Value}; } $self->{'__title'} = 1 if ($data->{Name} eq "title"); } sub end_element { my $self = shift; my $data = shift; return if ($self->{'__match'}); if ($data->{Name} eq "title") { $self->{'__title'} = 0; } if ($data->{Name} eq "bookmark") { $self->{'__bookmark'} = 0; } } sub characters { my $self = shift; my $data = shift; return if ($self->{'__match'}); return if (! $self->{'__bookmark'}); return if (! $self->{'__title'}); if ($data->{Data} eq $self->{'__keyword'}) { $self->{'__match'} = 1; } } package main; my $file = "/usr/home/asc/aaronland.net/asc/webdev.xbel"; use XML::SAX::ParserFactory; $XML::SAX::ParserPackage = "XML::SAX::Expat"; use Benchmark; my $count = 100; my @keywords = ( 'FilterProxy Home Page', "REX XML Shallow Parsing with Regular Expressions", "aaronland", "Schematron - XML Validation Language", ">RE ActivePerl mod_perl ppd available", ); timethese($count, { saxquery_expat => sub { foreach my $kw (@keywords) { my $filter = Foo->new(); $filter->keyword($kw); my $parser = XML::SAX::ParserFactory->parser(Handler=>$filter); $parser->parse_uri($file); } }, }); **** use XML::XPath; use Benchmark; my $file = "/usr/home/asc/aaronland.net/asc/webdev.xbel"; my $count = 100; my $xbel = XML::XPath->new(filename=>$file); my @keywords = ( 'FilterProxy Home Page', "REX XML Shallow Parsing with Regular Expressions", "aaronland", "Schematron - XML Validation Language", ">RE ActivePerl mod_perl ppd available", ); timethese($count, { xpathquery => sub { foreach my $title (@keywords) { my $query = "/xbel//bookmark[title=\"$title\"]/\@href"; my $r = $xbel->find($query); } }, });
Most common computer error.
ex. Oh, you have a "ID10T" error. (IDIOT)
(verb) The process of shortening phrases, via an acronym, for the purpose of simplifing statements. Typically used in technical data reporting or inter-office e-mails. (IE "FUBAR" or "KISS")
ex. I didn't realize that phrase had been acronyzed.

ex. As in a song lyric: Momma don't 'low no firkytoodlin' 'round here.
Slang Doritos. Sounds like "pete's."
ex. Pass my the retes.

doesn't work?! It does, but whatever... The kind words were nice and
appreciated, too. But if any of you think I'm touching the awards
controversy with a ten foot pole, you must be drooling uncontrollably.
Move along, now.
$MTCommentAuthorLink$
with automagically tags a name with some kind of URI, if present. You
can configure MT to force people to include an email address when they
submit a comment which, notwithstanding the ubiquitous
bob@bob.com
, is understandable. You can also include an optional URI. The problem
is that if you disallow anonymous comments and a user doesn't have, or
doesn't include, a URL their email address gets stuck into the anchor
tag. This is just bad form given the volume of spam-bots scraping the
web. There are two hacks around this problem. The first is to update
all your templates and change
$MTAuthorCommentLink$
to
$MTCommentAuthor$
, but this has the side-effect of never including an author's URL which
may be cause for further annoyance. The second is to alter the
conditional by hand, at lines 412-414, in MT::Template::Context.pm.
Neither of these options are really very satisfying, though. Rather,
this should be a configurable option in the mt.cfg file; something like
MTCommentsAtNoSpam
. Unfortunately, none of the objects contained in the
MT::Template::Context object contain instances of the MT::ConfigMgr
object. In the days to come, I will submit a bugfix to pass
$app->{ "cfg" }
as an argument to the Context.pm constructor...
