2) @key=‘ip’-还需要进行动态,从构造的t中获取一个值

<tr>

  <th>Type</th>
  <th>Text</th>

    <th><xsl:value-of select="current-grouping-key()"/></th>

  <xsl:for-each select="...">
    <td>
      <xsl:value-of select="string-join(property[@key='ip']/@value, ', ')"/>

元素和属性的数量是无限的,键的名称可能不同。

您可以使用 distinct-values 在这里获得不同的 property 钥匙,而不是 xsl:for-each-group

<xsl:variable name="properties" select="distinct-values(element/property/@key)" />

folder

然后,对于每个 element 在XML中,可以按如下方式列出属性的值

<xsl:variable name="current" select="." />
<xsl:for-each select="$properties">
<td>
  <xsl:value-of select="$current/property[@key=current()]/@value" separator=", " />
</td>
</xsl:for-each>

试试这个XSLT

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               exclude-result-prefixes="xsi">
    <xsl:output method="html" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />

    <xsl:template match="folder">
        <xsl:variable name="properties" select="distinct-values(element/property/@key)" />
        <table>
            <tr>
              <th>Name</th>
              <th>Type</th>
              <th>Text</th>
              <xsl:for-each select="$properties">
                <th><xsl:value-of select="."/></th>
              </xsl:for-each>
            </tr>
            <xsl:for-each select="element">
            <tr>
              <td>
                <xsl:value-of select="@name"/>
              </td>
              <td>
                <xsl:value-of select="@xsi:type"/>
              </td>
              <td>
                <xsl:value-of select="documentation"/>
              </td>
              <xsl:variable name="current" select="." />
              <xsl:for-each select="$properties">
                <td>
                  <xsl:value-of select="$current/property[@key=current()]/@value" separator=", " />
                </td>
              </xsl:for-each>
            </tr>
            </xsl:for-each>
        </table>
    </xsl:template>
</xsl:stylesheet>

xsi 命名空间前缀。我还在XSLT中声明它以进行检索 xsl:type

编辑:如果只能使用XSLT 1.0处理器,则无法使用去拿钥匙。相反,您需要使用一种称为 Muenchian Grouping 获取不同的键。(您也不能使用 separator 属性打开 xsl:value-of ).

请尝试以下XSLT:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               exclude-result-prefixes="xsi">
    <xsl:output method="html" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />

    <xsl:key name="properties" match="property" use="@key" />

    <xsl:template match="folder">
        <xsl:variable name="properties" select="//property[generate-id() = generate-id(key('properties', @key)[1])]/@key" />
        <table>
            <tr>
              <th>Name</th>
              <th>Type</th>
              <th>Text</th>
              <xsl:for-each select="$properties">
                <th><xsl:value-of select="."/></th>
              </xsl:for-each>
            </tr>
            <xsl:for-each select="element">
            <tr>
              <td>
                <xsl:value-of select="@name"/>
              </td>
              <td>
                <xsl:value-of select="@xsi:type"/>
              </td>
              <td>
                <xsl:value-of select="documentation"/>
              </td>
              <xsl:variable name="current" select="." />
              <xsl:for-each select="$properties">
                <td>
                  <xsl:for-each select="$current/property[@key=current()]/@value">
                    <xsl:if test="position() > 1">,</xsl:if>
                    <xsl:value-of select="." />
                  </xsl:for-each>
                </td>
              </xsl:for-each>
            </tr>
            </xsl:for-each>
        </table>
    </xsl:template>
