Re: group-starting-with drops child text nodes - work

sorry.

<xsl:template match="section">
    <xsl:copy >
        <xsl:for-each-group select="*" group-starting-with="subtitle">
            <xsl:choose>
                <xsl:when test="name(current-group()[1]) != 'subtitle'">
                    <xsl:apply-templates select="."/>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:element name="section">
                        <xsl:element name="h1">
                            <xsl:value-of select="."/>
                        </xsl:element>
                        <xsl:apply-templates select="current-group()[position() != 1]"/>
                    </xsl:element>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:for-each-group>
    </xsl:copy>
</xsl:template>


The idea is convert a <subtitle> to a <section> and drop the value of the subtitle into a following <h1>. eg

Input:

<test>
    <section>
    preamble
        <subtitle>section 1</subtitle>
            text
            <b>bolded text</b>
            more text
        <subtitle>section 2</subtitle>
    yet more text
    </section>
</test>


Desired output:

<test>
    <section>
    preamble
        <section>
            <h1>section 1</h1>
            text
            <b>bolded text</b>
            more text
        </section>
        <section>
            <h1>section 2</h1>
            yet more text
        </section>
    </section>
</test>



Actual output:

<test>
    <section>
        <section>
            <h1>section 1</h1>
            <b>bolded text</b>
        </section>
        <section>
            <h1>section 2</h1>
        </section>
    </section>
</test>

There are plenty of people on this list willing and able to show you how 
to fix your code. But first you need to show them your code. If it's not 
doing what you want, that's because you wrote it wrong.
