使用 Tidy 验证 PHP 中的 HTML5 文档

Validate HTML5 Document in PHP using Tidy

我正在尝试清理一个 HTML 字符串并使用 Tidy 和 PHP 创建一个 HTML5 文档,但是,我正在创建一个 HTML3.2 文档。如图所示,我收到 Config: missing or malformed argument for option: doctype 错误。我在 Centos 6 和 Apache 2.2 上运行 PHP 版本 5.5.35,php_info() 显示如下:

tidy

Tidy support    enabled
libTidy Release 14 June 2007
Extension Version   2.0 ($Id: e066a98a414c7f79f89f697c19c4336c61bc617b $)

Directive   Local Value Master Value
tidy.clean_output   no value    no value
tidy.default_config no value    no value

如何创建 HTML5 文档?以下是我的尝试:

<?php
$html = <<<EOD
<p>Hello</p>
<div>
 <p data-customattribute="will be an error">bla</p>
 <p>bla</p>
</div>
<div>
 <p>Hi there!</p>
 <div>
  <p>Opps, a mistake</px>
 </div>
</div>
EOD;
$html="<!DOCTYPE HTML><html><head><title></title></head><body>$html</body></html>";

echo($html."\n\n");

    $config = array(
        'indent' => true,
        'indent-spaces' => 4,
        'doctype' => '<!DOCTYPE HTML>',
    );

$tidy = new tidy;
$tidy->parseString($html, $config, 'utf8');
$tidy->cleanRepair();
print_r($tidy);

输出

<!DOCTYPE HTML><html><head><title></title></head><body><p>Hello</p>
<div>
 <p data-customattribute="will be an error">bla</p>
 <p>bla</p>
</div>
<div>
 <p>Hi there!</p>
 <div>
  <p>Opps, a mistake</px>
 </div>
</div></body></html>

Old versions of Tidy do not support HTML5 documents

第一个版本tidy支持HTML5是在Sep 2015, where the HTML Tidy Advocacy Community Group发布第一个tidy-html5版本。

请注意,您使用的是旧版本的 tidy,因此您将无法验证 html5 个文档。

php 的当前预编译版本尚未使用 tidy-html5 进行编译,因此如果您想使用 tidy-html5,则必须自己进行编译。

这些说明取自 tidy-html5 github:

中的 README 文件

Due to API changes in the PHP source, "buffio.h" needs to be changed to "tidybuffio.h" in the file ext/tidy/tidy.c.

That is - prior to configuring php run this in the php source directory:

   sed -i 's/buffio.h/tidybuffio.h/' ext/tidy/*.c

And then continue with (just an example here, use your own php config options):

   ./configure --with-tidy=/usr/local
   make
   make test
   make install
