晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

=head1 NAME
XML::LibXML::RegExp - XML::LibXML::RegExp - interface to libxml2 regular expressions
=head1 SYNOPSIS
use XML::LibXML;
my $compiled_re = XML::LibXML::RegExp->new('[0-9]{5}(-[0-9]{4})?');
if ($compiled_re->isDeterministic()) { ... }
if ($compiled_re->matches($string)) { ... }
$compiled_re = XML::LibXML::RegExp->new( $regexp_str );
$bool = $compiled_re->matches($string);
$bool = $compiled_re->isDeterministic();
=head1 DESCRIPTION
This is a perl interface to libxml2's implementation of regular expressions,
which are used e.g. for validation of XML Schema simple types (pattern facet).
=over 4
=item new()
$compiled_re = XML::LibXML::RegExp->new( $regexp_str );
The constructor takes a string containing a regular expression and returns a
compiled regexp object.
=item matches($string)
$bool = $compiled_re->matches($string);
Given a string value, returns a true value if the value is matched by the
compiled regular expression.
=item isDeterministic()
$bool = $compiled_re->isDeterministic();
Returns a true value if the regular expression is deterministic; returns false
otherwise. (See the definition of determinism in the XML spec (L<<<<<< http://www.w3.org/TR/REC-xml/#determinism >>>>>>))
