我有一个asp.net Web应用程序。应用程序从xml读取数据。 xml引用了一个xslt文件，它负责表的设计和对齐。我以动态方式向xml添加数据。 我希望表格的每个替代行都有一个颜色（比如灰色）以便于阅读。我相信它可以在xslt本身使用代码行
完成 <xsl:if test="(position() mod 2 = 0)">
有人可以告诉我怎么做吗？我已将xslt完全发布在下方。

答案 0 :(得分：2)
你实际上是在正确的轨道上。分配编号的css类并使用position（）mod 2来计算要调用的css类。
以下是演示：
<?xml version="1.0" encoding="utf-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output version="1.0" encoding="utf-8" indent="yes" method="html"/>
<xsl:template match="/">
<xsl:variable name="sortValue">title</xsl:variable>
<style type="text/css">
.row0 { background-color: blue; }
.row1 { background-color: red; }
</style>
<table border='1'>
<tr>
<th>ID</th>
<th>Artist</th>
<th>Title</th>
<th>Album</th>
<th>Length</th>
</tr>
<xsl:for-each select="*/song">
<xsl:variable name="rowClass">
row <xsl:number value="position() mod 2"/>
</xsl:variable>
<tr>
<td class="{$rowClass}"><xsl:value-of select="./@id"/></td>
<td class="{$rowClass}"><xsl:value-of select="./artist"/></td>
<td class="{$rowClass}"><xsl:value-of select="./title"/></td>
<td class="{$rowClass}"><xsl:value-of select="./album"/></td>
<td class="{$rowClass}"><xsl:value-of select="./length"/></td>
</tr>

HTH。
