这段是XML文件，文件名为movies.xml
如下所示：
<?xml version="1.0" encoding="GB2312"?>
<?xml-stylesheet type="text/xsl" href="style.xsl"?>
<movielist>
    <movie>
        <title>英雄</title>
        <player>李连杰</player>
        <player>梁朝伟</player>
     <player>张曼玉</player>
     <player>章子怡</player>
     <player>陈道明</player>
        <time>135分钟</time>
     <producer>新画面影业</producer>
        <summary>战国末期</summary>
    </movie>
    <movie>
        <title>手机</title>

     <producer>八一电影制片厂</producer>
        <summary>抗日战争时期</summary>
    </movie>
</movielist>

这段就是style.xsl文件，代码如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">
    <xsl:template match="/">
        <xsl:for-each select="movielist/movie">
               <xsl:value-of select="title"/><br/>
                <xsl:value-of select="time"/><br/>
               <xsl:value-of select="producer"/><br/>
               <xsl:value-of select="summary"/><br/>
        </xsl:for-each>    
    </xsl:template>
</xsl:stylesheet>

我的问题是，为什么在浏览器中运行movies.xml的时候，通过了编译，但是就是什么都不显示，这是怎么回事啊？哪里出错了，请高手指教，谢谢！

我把<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">
换成了<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
结果就显示出来了！！！

但是我不明白，原先那个命名空间为什么不好用啊？书上都是那么写的啊！
我怎么才能知道什么时候该用哪个命名空间呢？
望赐教一二！谢谢！

This namespace preceded the use of http://www.w3.org/1999/XSL/Transform for XSLT. Original Microsoft XSLT implementation referred to this namespace, the final release of MSXML 3.0 already implements the final one.
The draft containing this namespace defined an early version of XSLT 1.0, which had changed dramatically till the final release. This namespace should be used very cautiously and only if compatibility with older releases of Internet Explorer 5 is required.
