Perl 最好的 XML 解析器是什么？

What's the best XML parser for Perl?

提问by Xetius

I have tried many of the Perl XML Parsers. I was quite interested in the Sablotron Parser, but it is such a pain to install on a Windows box. Currently I have started using XML::LibXMLand XML::LibXSLTboth of which seem to do everything I need.

我尝试了许多 Perl XML 解析器。我对 Sablotron Parser 非常感兴趣，但是在 Windows 机器上安装它是如此痛苦。目前我已经开始使用XML::LibXML和XML::LibXSLT，这两者似乎都能满足我的需求。

They seem to be quite standard as well. Are there any better XML Parsers to use than this?

他们似乎也很标准。还有比这更好的 XML 解析器吗？

I think you are using a pretty good one. XML::LibXML, Matt Sergeant and Christian Glahn's Perl interface to Daniel Velliard's libxml2is one of the faster XML Parsers that I know of.

我认为你正在使用一个很好的。 XML::LibXML、Matt Sergeant 和 Christian Glahn 与 Daniel Velliard 的libxml2的 Perl 接口是我所知道的更快的 XML 解析器之一。

It really depends on your needs, as people have said. To parse XML files that were ~100Mb in size (gene annotations from TAIR, 1 file per chromosome), I used mirod's XML::Twigmodule, which lets you set callbacks to parse the elements that interest you, presenting each sub-document as an XML::Simple tree. It combines the benefits of a SAX parser (scanning the file as a stream) with a DOM parser (working more easily with the interesting pieces).

正如人们所说，这真的取决于您的需求。为了解析大约 100Mb 的 XML 文件（来自TAIR 的基因注释，每个染色体 1 个文件），我使用了 mirod 的XML::Twig模块，它允许您设置回调来解析您感兴趣的元素，将每个子文档呈现为一个 XML::Simple 树。它结合了 SAX 解析器（将文件作为流扫描）和 DOM 解析器（更容易处理有趣的部分）的优点。

If you need speed, power or features, XML::LibXML is the way to go. If you're after ease of use, though, XML::Simpleis a viable alternative.

如果您需要速度、功能或功能，XML::LibXML 是您的最佳选择。不过，如果您追求易用性，那么XML::Simple是一个可行的替代方案。

In my experience XML::Simpleis best for quick and dirty parsing of XML. We use it for parsing data from third parties that do not always conform to the XML standard. XML::Simple throws informative errors and gets you up an running extremely quickly.

根据我的经验，XML::Simple最适合快速且脏地解析 XML。我们使用它来解析不总是符合 XML 标准的第三方数据。XML::Simple 会抛出信息性错误并让您非常快速地开始运行。

(Actually it's not an answer, but a comment - however, I cannot comment...)

（实际上这不是答案，而是评论-但是，我无法发表评论......）

XML::Simple has been mentioned here.
(I know it's few from few years ago, but this appeared up in Google today...)

XML::Simple 已在此处提及。
（我知道几年前很少，但今天出现在谷歌......）

However, it's site (http://metacpan.org/pod/XML::Simple) now says:

但是，它的站点（http://metacpan.org/pod/XML::Simple）现在说：

STATUS OF THIS MODULE

本模块的状态

The use of this module in new code is discouraged. Other modules are available which provide more straightforward and consistent interfaces. In particular, XML::LibXML is highly recommended.

不鼓励在新代码中使用此模块。其他模块可提供更直接和一致的接口。特别是，强烈推荐使用 XML::LibXML。

The major problems with this module are the large number of options and the arbitrary ways in which these options interact - often with unexpected results.

这个模块的主要问题是大量的选项和这些选项交互的任意方式——通常会产生意想不到的结果。

Patches with bug fixes and documentation fixes are welcome, but new features are unlikely to be added.

欢迎使用带有错误修复和文档修复的补丁，但不太可能添加新功能。

You could also look at XML::Liberalwhich uses LibXML underneath.

您还可以查看在下面使用 LibXML 的XML::Liberal。

I think you should give XML::MyXMLa try, too. It's very easy to use.

我认为您也应该尝试一下XML::MyXML。它非常容易使用。

回答by HoldOffHunger

I'll offer one that SHOULD NOTbe used: XML::Parser.

我将提供一个不应该使用的：XML::Parser。

It automatically expands HTML entities to their UTF-8 equivalents, and the option to disable this behavior does not work on the most characteristic of all entities, &.

它会自动将 HTML 实体扩展为它们的 UTF-8 等效项，并且禁用此行为的选项不适用于所有实体中最具特征的&.

Additionally, its XMLDecl-parser will interpret and display the standaloneattribute in the <?xml ... ?>block as "standalone"="1", which is absolutely incorrect -- it should be "standalone"="yes".

此外，它的 XMLDecl 解析器会将块中的standalone属性解释并显示<?xml ... ?>为"standalone"="1"，这是绝对不正确的——它应该是"standalone"="yes"。
