CXLV. Tidy Functions
简介
Tidy is a binding for the Tidy HTML clean and repair utility which allows you to not only clean and otherwise manipulate HTML documents, but also traverse the document tree.
需求
To use Tidy, you will need libtidy installed, available on the tidy homepage http://tidy.sourceforge.net/.
安装
Tidy is currently available for PHP 4.3.x and PHP 5 as a PECL extension from http://pecl.php.net/package/tidy.
注: Tidy 1.0 is just for PHP 4.3.x, while Tidy 2.0 is just for PHP 5.
If PEAR is available on your *nix-like system you can use the pear installer to install the tidy extension, by the following command: pear -v install tidy.
You can always download the tar.gz package and install tidy by hand:
Windows users can download the extension dll php_tidy.dll from http://snaps.php.net/win32/PECL_STABLE/.
In PHP 5 you need only to compile using the --with-tidy option.
运行时配置
这些函数的行为受 php.ini 的影响。

预定义类
tidyNode
方法
tidyNode->hasChildren - Returns TRUE if the current node has childrens
tidyNode->hasSiblings - Returns TRUE if the current node has siblings
tidyNode->isAsp - Returns TRUE if the current node is ASP code
tidyNode->isComment - Returns TRUE if the current node is a comment
tidyNode->isHtml - Returns TRUE if the current node is HTML
tidyNode->isJste - Returns TRUE if the current node is JSTE
tidyNode->isPhp - Returns TRUE if the current node is PHP
tidyNode->isText - Returns TRUE if the current node is Text (no markup)
属性
value - the value of the node (e.g. the html text)
name - the name of the tag (e.g. html, a, etc..)
type - the type of the node (one of the constants above, e.g. TIDY_NODETYPE_PHP)
line* - the line where the node starts
column* - the column where the node starts
proprietary* - TRUE if the node refers to a proprietary tag
id - the ID of the tag (one of the constants above, e.g. TIDY_TAG_FRAME)
attribute - an array with the attributes of the current node, or NULL if there aren't any
child - an array with the child tidyNodes, or NULL if there aren't any
注: The properties marked with * are just available since PHP 5.1.0.
预定义常量
以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。
Each TIDY_TAG_XXX represents a HTML tag. For example, TIDY_TAG_A represents a <a href="XX">link</a> tag. Each TIDY_ATTR_XXX represents a HTML atribute. For example TIDY_ATTR_HREF would represent the href atribute in the previous example.
The following constants are defined:
