感谢How to use XSLT to convert a XML to Table [CODE UPDATED 11/6]，现在我可以通过XSLT将xml转换为表，但是当我添加一个嵌套循环时，结果没有完全加载，我不确定出了什么问题。

我添加的嵌套循环是
<xsl:for-each select="../../../RoleDetail/Roles/OccTitle">
<xsl:variable name="roleval" select="."/>
...
</xsl:for-each>
这个用于数据，这个节点可能会也可能不会进入（XML数据文件），如果这个节点没有进入XML，只需将其留空，否则它也应该循环。
<RoleDetail>
<Roles RoleType="Primary">
<OccTitle SinceDay="17" SinceMonth="Nov" SinceYear="2009" OccCat="6">Thai</OccTitle>
</Roles>
</RoleDetail>
现在，问题是＆＃34;最后两行＆＃34;没有显示和Col OccTitle，SinceDay和SinceMonth也是空的 非常感谢
答案 0 :(得分：0)
执行此操作时：
<xsl:for-each select="../../../RoleDetail/Roles/OccTitle">
<xsl:variable name="roleval" select="."/>
$roleval变量绑定到OccTitle元素。因此，您需要更改这些：
<td>
<xsl:value-of select="$roleval/OccTitle"/>
</td>
<td>
<xsl:value-of select="$roleval/OccTitle/@SinceDay"/>
</td>
<td>
<xsl:value-of select="$roleval/OccTitle/@SinceMonth"/>
</td>
为：
<td>
<xsl:value-of select="$roleval"/>
</td>
<td>
<xsl:value-of select="$roleval/@SinceDay"/>
</td>
<td>
<xsl:value-of select="$roleval/@SinceMonth"/>
</td>
恕我直言，您应该将变量$occTitle命名为更清晰，从而避免这种错误。
此节点可能会或可能不会（XML数据文件）
我担心这是一个完全不同的问题。你在这里有一种多维矩阵 - 如果其中一个维度是0，那么整个矩阵将是空的。
