导读：我在做什么：我正在尝试使用xslt将xml转换为html. 问题：程序正在执行而没有任何错误,它也会生成输出文件,但它不会将xml转换为html.我的猜测是xsl中的for循环不是获取数据. XSLTTest.java package JavaXSLTExample;import javax.xml.transform.ErrorListener

问题：程序正在执行而没有任何错误,它也会生成输出文件,但它不会将xml转换为html.我的猜测是xsl中的for循环不是获取数据.

    XSLTTest st = new XSLTTest();
    try

FileTwo.xsl

    <xsl:template match="/">
        <html>
            <body>
                <h1>Indian Languages details</h1>
                <table border="1">

                </table>
            </body>
        </html>
    </xsl:template>
</xsl:stylesheet>

Output.html

<html>
<body>
<h1>Indian Languages details</h1>
<table border="1">
<tr>
<th>Language</th><th>Family/Origin</th><th>No. of speakers</th><th>Region</th>
</tr>
</table>
</body>
</html>

解决方法

XML非常无情.这个：

<xsl:for-each select="language-list/language">

需要是：

<xsl:for-each select="languages-list/language">
