# XSL(内置)
安装:内置扩展,默认为开启,需要在php.ini手动开启
xml是标记语言,用描述和保存数据。
xsl是扩展样式表语言,xsl是将xml变形的,将数据转换成html页面。
**它起始于 XSL,结束于 XSLT、XPath 以及 XSL-FO。**
> ## CSS 是 HTML 样式表,而XSL是XML 样式表
### XSL 包括三部分:
XSLT
一种用于转换 XML 文档的语言或其他 XML 文档的语言。
XPath
一种用于在 XML 文档中导航的语言。
XSL-FO
一种用于格式化 XML 文档的语言。
声明 XSL 样式表的正确方法是:
```
<pre class="calibre10">```
<span class="token1"><</span>xsl<span class="token3">:</span>stylesheet version<span class="token1">=</span><span class="token2">"1.0"</span> xmlns<span class="token3">:</span>xsl<span class="token1">=</span><span class="token2">"http://www.w3.org/1999/XSL/Transform"</span><span class="token1">></span>

```
或者:
