HTML::TableExtract:如何运行正确的参数 [参见实例]

关于解析器的问题。是否有机会捕获分隔表格的一些分隔符...paser 脚本运行良好。注意 - 我想将数据存储到 MySQL 数据库中。因此,最好有一些分隔符 - (逗号、制表符或其他形式 - 制表符分隔值或逗号分隔值 是方便使用的格式...

好吧,我需要将这些行分成至少三列 - 取第一条记录。

名称:国民学校 阿贝贝格(Grundschule)街: 古苏贝尔街2 邮政编码和城镇: 91183阿贝格传真和电话: 09178/215 09178/905060 类型 学校:Volksschulen 网站: home.t-online.de/home/vs-abenberg

或者甚至更好 - 我已将邮政编码和城镇分成两个单独的列!? 问题:这可能吗?

顺便:看第一条记录:(这里我只显示学校名称)

1 0401 Mädchenrealschule 马里恩堡,阿本贝格,6 3074 私人 Berufsschule zur sonderpäd。福德隆, 阿本斯贝格 Förderschwerpunkt Lernen

名称中包含一些逗号;这是否会使创建一个创建 csv-fomate 的解析器变得困难?

知道如何在 Perl 中做到这一点...如果可能的话那就太好了! 非常感谢有关这个小问题的提示 - 除此之外,一切都很棒且令人着迷!

顺便说一句 - 如果你愿意 - 我可以添加代码。这里没问题。

A question regarding a parser. Is there any chance to catch some separators within the that separate the table... The paser script runs allready nicely. Note - i want to store the data into a MySQL database. So it would be great to have some seperators - (commas, tabs or somewhat else - a tab seperated values or comma seperated values
are handy formats to work with...

Well i need to have those lines divided into at least three columns - take the first record.

name: Volksschule
Abenberg (Grundschule) street:
Güssübelstr. 2 postal-code and town:
91183  Abenberg fax and telephone:
09178/215 09178/905060 type of
school: Volksschulen website:
home.t-online.de/home/vs-abenberg

Or even better - i have divided the postal-code and town into two seperate columns!?
Question: is this possible?

By the way: see the first record: (here i only show the names of the school)

1 0401 Mädchenrealschule
Marienburg, Abenberg, 6 3074 Private
Berufsschule zur sonderpäd. Förderung,
Förderschwerpunkt Lernen, Abensberg

Those have some commas inside the name; does this make it difficult to create a parser that creates csv-fomate?

any idea how to do this in Perl... If possible it would be just great!!
many many thx for a hint regarding this little issue - besides this all is great and fascinating!

zero

BTW - if you want - i can add the code. No problem here.

我建议使用 HTML::Parser 模块,您可以调整该模块以提取表格单元格的值。请参阅文档:
http://search.cpan.org/perldoc?HTML::Parser

I recommend the use of HTML::Parser module, which you can adjust in order to extract the values of the table cells. See documentation:
