Question

我按顺序排列元素。我需要根据sec值对元素进行分组。下面我提到了我的意见。

    <body>
    <title>first</title>
    <entry><sec>s 2</sec><p><text>some text 1</text></p></entry>
    <entry><sec>s 3</sec><p><text>some text 2</text></p></entry>
    <section>section title</section>
<entry><sec>Sh 1</sec><p><text>some text 3</text></p></entry>
    <entry><sec>Sh 1<sub>Pt 2</sub></sec><p><text>some text 4</text></p></entry>
    <entry><sec>Sh 1<sub>item 1</sub></sec><p><text>some text 5</text></p></entry>
    <entry><sec>s 8</sec><p><text>some text 2</text></p></entry>
    <entry><sec>s 9</sec><p><text>some text 2</text></p></entry>
    <entry><sec>Sh 2<sub>item 2</sub></sec><p><text>some text 10</text></p></entry>
    <entry><sec>Sh 2</sec><p><text>some text 20</text></p></entry>
    </body>

我期待以下输出。

 <body>
<title>first</title>
    <entry><sec>s 2</sec><p><text>some text 1</text></p></entry>
    <entry><sec>s 3</sec><p><text>some text 2</text></p></entry>
<section>section title</section>
    <group>
    <entry><sec>Sh 1</sec><p><text>some text 3</text></p></entry>
    <entry><sec>Sh 1<sub>Pt 2</sub></sec><p><text>some text 4</text></p></entry>
    <entry><sec>Sh 1<sub>item 1</sub></sec><p><text>some text 5</text></p></entry>
    </group>
    <entry><sec>s 8</sec><p><text>some text 2</text></p></entry>
    <entry><sec>s 9</sec><p><text>some text 2</text></p></entry>
    <group>
    <entry><sec>Sh 2<sub>item 2</sub></sec><p><text>some text 10</text></p></entry>
    <entry><sec>Sh 2</sec><p><text>some text 20</text></p></entry>
    </group>
    </body>

请尽力帮助我。

您可以尝试：

<xsl:template match="body">
    <body>
    <xsl:for-each-group select="entry" 
        group-adjacent="starts-with(sec, 'Sh ')">
        <xsl:choose>
            <xsl:when test="current-grouping-key()">
                <group>
                <xsl:copy-of select="current-group()"/>
                </group>
            </xsl:when>
            <xsl:otherwise>
                    <xsl:copy-of select="current-group()"/>
            </xsl:otherwise>  
        </xsl:choose>
    </xsl:for-each-group>
    </body>
</xsl:template>

<强>输出

    <body>
    <entry><sec>s 2</sec><p><text>some text 1</text></p></entry>
    <entry><sec>s 3</sec><p><text>some text 2</text></p></entry>
    <group>
    <entry><sec>Sh 1</sec><p><text>some text 3</text></p></entry>
    <entry><sec>Sh 1<sub>Pt 2</sub></sec><p><text>some text 4</text></p></entry>
    <entry><sec>Sh 1<sub>item 1</sub></sec><p><text>some text 5</text></p></entry>
    </group>
    <entry><sec>s 8</sec><p><text>some text 2</text></p></entry>
    <entry><sec>s 9</sec><p><text>some text 2</text></p></entry>
    <group>
    <entry><sec>Sh 2<sub>item 2</sub></sec><p><text>some text 10</text></p></entry>
    <entry><sec>Sh 2</sec><p><text>some text 20</text></p></entry>
    </group>
</body>

如果组中只有一个项目，则不想包装项目，请使用

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">


    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

     <xsl:template match="body"> 
       <xsl:copy>
                  <xsl:for-each-group select="entry" group-by="sec/text()[1]"> 
                    <xsl:choose>
                        <xsl:when test="current-group()[2]">
                            <group>
                              <xsl:apply-templates select="current-group()"/>                                
                            </group>
                        </xsl:when>
                        <xsl:otherwise>
                            <xsl:apply-templates select="."/>
                        </xsl:otherwise>
                    </xsl:choose>
                </xsl:for-each-group>
       </xsl:copy>

       </xsl:template>
</xsl:transform>
