xmp
适用DTD： 适用浏览器：All
释义
保持文件格式且不运行元素标签（example）
语法
<xmp 属性="属性值">~标签内容~</xmp>
<xmp 属性="属性值">~标签内容~</xmp>
说明
该元素可以保持文字间的相对位置，将要显示的文字格式完全对应地显示在浏览器中，固定大小的字型空格及空白行不会被省略。这一点和pre元素是相同的。
xmp会忽略其开始标签与终止标签之间的任何元素标签，所有的HTML标记都会被忽略，但其终止标签及其终止标签之后的元素则不受影响。这一点与plaintext极相似但又不全相同
xmp在HTML 4.0后已被列入非标准元素（已从HTML 4.0标准中去除），建议以pre取代
xmp元素中的文字默认不会自动换行，如果一行文字过长，浏览器将产生水平滚动条。xmp元素的标签内容也会以等宽字体显示

<xmp>The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:
May leave white space intact.
May render text with a fixed-pitch font.
May disable automatic word wrap.
Must not disable bidirectional processing.
Non-visual user agents are not required to respect extra white space in the content of a PRE element.

Non-visual user agents are not required to respect extra white space in the content of a PRE element.
The DTD fragment above indicates which elements may not appear within a PRE declaration. This is the same as in HTML 3.2, and is intended to preserve constant line spacing and column alignment for text rendered in a fixed pitch font. Authors are discouraged from altering this behavior through style sheets.
