<p class="MsoNormal"><span style="FONT-FAMILY: 宋体">两行重要的代码已突出显示。首先，在给</span><span lang="EN-US">XsltArgumentList</span><span style="FONT-FAMILY: 宋体">添加对象时，添加了前面创建的命名空间。然后，在调用方法时，使用标准的</span><span lang="EN-US">XSLT</span><span style="FONT-FAMILY: 宋体">命名空间前缀语法。</span></p>
<p class="MsoNormal"><span style="FONT-FAMILY: 宋体">另一种方式是使用</span><span lang="EN-US">XSLT</span><span style="FONT-FAMILY: 宋体">脚本。可以在该样式表中包含</span><span lang="EN-US">C#</span><span style="FONT-FAMILY: 宋体">、</span><span lang="EN-US">VB</span><span style="FONT-FAMILY: 宋体">和</span><span lang="EN-US"> JavaScript</span><span style="FONT-FAMILY: 宋体">代码。最重要的是在</span><span lang="EN-US">Transform.Load</span><span style="FONT-FAMILY: 宋体">调用中编译该脚本，这与目前的非</span><span lang="EN-US">.NET</span><span style="FONT-FAMILY: 宋体">实现不同。这样就可以执行已经编译好的脚本，与</span><span lang="EN-US">ASP.NET</span><span style="FONT-FAMILY: 宋体">的工作方式相同。</span></p>
