Perl 如何使XML:：RSS:：Parser从URL而不是文件获取输入,perl,xml-parsing,Perl,Xml Parsing,我有一个简短的Perl脚本，用于从XML文件中提取一些信息 #!/usr/bin/perl -w use strict; use XML::RSS::Parser; use FileHandle; use Data::Dumper; use URI; my $p = XML::RSS::Parser->new; my $fh = FileHandle->new('ronicky-doone-by-max-brand.xml'); my $feed = $p->parse_

我有一个简短的Perl脚本，用于从XML文件中提取一些信息

#!/usr/bin/perl -w
use strict;

use XML::RSS::Parser;
use FileHandle;
use Data::Dumper;
use URI;

my $p = XML::RSS::Parser->new;
my $fh = FileHandle->new('ronicky-doone-by-max-brand.xml');

my $feed = $p->parse_file( $fh );
print $p->errstr;

my $feed_title = $feed->query('/channel/title');
print $feed_title->text_content;

my $feed_desc = $feed->query('/channel/description');
print $feed_desc->text_content;

我知道有一个

parse_uri

方法，但我似乎无法将我的URL转到

http://librivox.org/bookfeeds/ronicky-doone-by-max-brand.xml

转换为URI，我可以将参数传递给

XML:：RSS:：Parser:：parse_URI

我不知道你试过什么，但很简单。也许使用

FileHandle

会让你感到困惑

这个版本的代码可以正常工作。请注意，

-w

命令行选项在许多年前被

使用警告

取代，除了简短的命令行Perl程序。此外，我还必须设置

STDOUT

以期望UTF-8，因为这个RSS提要中有一些扩展字符

use strict;
use warnings;

use XML::RSS::Parser;

binmode STDOUT, ':encoding(UTF-8)';

my $parser = XML::RSS::Parser->new;
my $feed = $parser->parse_uri('http://librivox.org/bookfeeds/ronicky-doone-by-max-brand.xml');

printf "Title: %s\n", $feed->query('/channel/title')->text_content;

printf "Description: %s\n", $feed->query('/channel/description')->text_content;

输出

Title: Librivox: Ronicky Doone by Brand, Max
Description:  Frederick Schiller Faust (1892-1944), is best known today for his western fiction. Faust was born in Seattle, Washington and at an early age moved with his parents to the San Joaquin Valley in California where he worked as a ranchhand. After a failed attempt to enlist in the Great War in 1917 and with the help of Mark Twain's sister he met Robert Hobart Davis, editor of All-Story Weekly and became a regular contributor writting under his most used pseudonym â€œMax Brandâ€. He wrote in many genres during his career and produced more than 300 western novels and stories. His most famous characters were Destry and Dr. Kildare, both of which were produced in film. Faust was killed in Italy in 1944 as a front line war correspondent at the age of 51. He is buried in the Sicily-Rome American Cemetery in Nettuno, Italy.

Ronicky Doone (1926) is a hero of the west, respected by the law-abiding citizen and hated by bushwhacking bandits. Bill Gregg is a man in love, not about to be deflected from meeting his lady love for the first time, and willing to stand up to the living legend to reach her. This initial meeting leads to a friendship between the two and they travel east to New York City on the trail of the girl. When they find the girl, Caroline Smith, and she refuses to leave, Ronicky must discover the secret that holds her. They encounter the sinister John Mark and the beautiful Ruth Tolliver and are exposed to the horrors and vices of big city life as they attempt to rescue Caroline and find their way back to the mountain-desert of the west.
