追加一个新的子节点，创建一个新行？答案

【问题标题】：Append a new child node, create a new row?追加一个新的子节点，创建一个新行？
【发布时间】：2016-12-12 19:53:22
【问题描述】：

我是 XSL 的新手，我正在尝试创建一个 XSL 来创建一个 cmets 表。这将是一个不断更新的 xml，其中添加了 cmets。

我已经找到了基本表并且对此很满意，但是如果将新注释附加到现有视图节点，我希望它显示为另一个行项目。相同的视图名称，相同的子节点名称但具有不同的子节点值。下面是我的 XML、XSL 和当前 HTML 输出以及我想要的 HMTL 输出的示例。谁能指出我正确的方向？

提前致谢！

【问题讨论】：

所有divs 的意义何在？
我明白你的意思，现在看，它们真的没有任何意义！

【解决方案1】：

如果您希望表中每个 comment 都有一行，则为每个 comment 创建一行 - 例如：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/exchange">
    <html>
        <body>
            <h2>Comments</h2>
            <table border="1">
                <tr>
                    <th>View Name</th>
                    <th>Comment Status</th>
                    <th>User</th>
                    <th>Comment</th>
                </tr>
                <xsl:apply-templates select="viewpoints/view/comments/comment"/>
            </table>
        </body>
    </html>
</xsl:template>

<xsl:template match="comment"> 
    <tr>  
        <td>
            <xsl:value-of select="../../@name"/>
        </td>
        <td>
            <xsl:value-of select="@status"/>
        </td>
        <td>
            <xsl:value-of select="user"/>
        </td>
        <td>
            <xsl:value-of select="body"/>
        </td>
    </tr>
</xsl:template>

</xsl:stylesheet>
