??例程中使用XSL对XMl数据进行格式化,并以HTML的形式返回到客户端。这个过程也可以放在客户端进行,但考虑到兼容性的问题,例程中采用了在服务器端通过ASP操纵DOM进行格式化的方法。
??XSL文件的内容如下,
<?xml version="1.0" encoding="gb2312"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/Persons">
<script language="javascript">
function add()
{
window.open("add.asp", "add", "width=300,height=320,resize=no");
}
function edit(intId)
{
window.open("edit.asp?id="+intId, "edit", "width=300,height=320,resize=no");
}
</script>
<table width="600" border="0" align="center">
<tr>
<td align="right"><a href="javascript:add();" title="添加新联系人">添加新联系人</a> </td>
</tr>
</table>
<table align="center" width="680" cellspacing="1" cellpadding="2" border="0" bgcolor="#666600">
<tr class="title" bgcolor="#E5E5E5">
<td width="25"><xsl:text disable-output-escaping="yes">&</xsl:text>nbsp;</td>
<td>姓名</td>
<td>英文名</td>
<td>手机</td>
<td>电话</td>
<td>Email</td>
<td>QQ</td>
<td>所在公司</td>
</tr>
<xsl:for-each select="Person">
<TR BGCOLOR="#FFFFFF">
<TD ALIGN="right"><xsl:value-of select="position()"/></TD>
<TD STYLE="color:#990000"><A><xsl:attribute name="HREF">javascript:edit('<xsl:value-of select="position()"/>');</xsl:attribute><xsl:attribute name="title">修改信息 </xsl:attribute><xsl:value-of select="Name"/></A></TD>
<TD><xsl:value-of select="Nick"/></TD>
<TD><xsl:value-of select="Mobile"/></TD>
<TD><xsl:value-of select="Tel"/></TD>
<TD><A><xsl:attribute name="HREF">mailto:<xsl:value-of select="Email"/></xsl:attribute><xsl:value-of select="Email"/></A></TD>

</TR>
</xsl:for-each>

</xsl:template>
</xsl:stylesheet>
??在服务器端的转换使用一个函数来完成,格式化成功,返回HTML字符串,格式化失败,打印出错误信息,如下,
