SyntaxHighlighter是一个非常不错的代码高亮工具，支持各种平台，只需要前台载入代码即可。
第一步：
1、引入需要的js和css
     <script type="text/javascript" src="scripts/shCore.js"></script>
     <link type="text/css" rel="stylesheet" href="styles/shCore.css"/>
     <link type="text/css" rel="stylesheet" href="styles/shThemeDefault.css"/>
这三个是必须的，如果需要给xml代码高亮显示，则需要引入xml相关的js。
<script type="text/javascript" src="scripts/shBrushXml.js"></script>



这个是css需要的js
<script type="text/javascript" src="scripts/shBrushCss.js"></script>
这个是java需要的js
<script type="text/javascript" src="scripts/shBrushJava.js"></script>
这个是javascript需要的js
<script type="text/javascript" src="scripts/shBrushJScript.js"></script>
这个是sql需要的js
<script type="text/javascript" src="scripts/shBrushSql.js"></script>


2、在页面初始化时调用如下js代码：
SyntaxHighlighter.all();

3、将xml代码放入<pre class="brush:xml;"></pre>标签内部。如此就可以高亮显示xml代码。

		//鼠标移动到代码区域时会显示一个工具条，默认为英文，改中文设置如下：
		SyntaxHighlighter.config.strings = {

            expandSource : '展开代码',

            viewSource : '查看代码',

            copyToClipboard : '复制代码',

            copyToClipboardConfirmation : '代码复制成功',

            print : '打印',

            help: '?'
        };
		
		//代码显示在标签为<pre></pre>中，syntaxhighlighter默认会自动查找<pre/>标签，其中标签可自定义，只需要加上如下配置代码
		//SyntaxHighlighter.config.tagName="textarea";
		
		//有些场景下不想显示工具条，有两种解决方案：
		//1、SyntaxHighlighter.defaults.toolbar=false;
		//2.在pre标签的class属性里添加toolbar:false;(<pre class="brush:xml;toolbar:false;">)
		//SyntaxHighlighter.defaults.toolbar=false;
		SyntaxHighlighter.all();
	</script>
