XSLT to select and transform node (with regex match) and following siblings until next similar node

Question

Somewhat simplified, my XML looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<dict>
    <entry>
        <form>word</form>
        <gram>noun</gram>
        <span style="bold">1.</span>
        <def>this is a definition in the first sense.</def> – <cit type="example">
            <quote>This is a <span style="bold">quote</span> for the first sense. </quote>
        </cit>
        <span style="bold">2.</span>
        <def>This is a definition for the second sense</def> – <cit type="example">
            <quote>This is a quote for the second sense.</quote>
        </cit>
    </entry>    
</dict>

I need to transform this using XSLT 2.0 or 3.0 to get the following:

<?xml version="1.0" encoding="UTF-8"?>
<dict>
    <entry>
        <form>word</form>
        <gram>noun</gram>
        <sense n="1">
            <def>this is a definition in the first sense.</def> – <cit type="example">
                <quote>This is a <span style="bold">quote</span> for the first sense. </quote>
            </cit>
        </sense>
        <sense n="2">
            <def>This is a definition for the second sense</def> – <cit type="example">
                <quote>This is a quote for the second sense.</quote>
            </cit>
        </sense>
    </entry>
</dict>

Тhere can be more than two senses, and span style bold can occur elsewhere, so we need to identify specifically something like tei:span[@style='bold'][matches(text(), '^\d\.')] for this.

I'm having a hard time putting this together in a stylesheet that would also extract the number for the span's text node and use it as the attribute value of the new element <sense>.

I'll be most grateful for your tips.x

Can you extend your example to include the case where "span style bold can occur elsewhere" to show how that should be handled (assuming you don't want a `sense` element for it)? Thanks! — Tim C, Feb 10 '17 at 11:52
I just did — span style bolds are used to make some words bold, but if they are used as sense delimiters, they always contain only a number and a period. — Tench, Feb 10 '17 at 11:58

Here is an XSLT 3.0 sample

<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs">

    <xsl:mode on-no-match="shallow-copy"/>

    <xsl:output indent="yes"/>

    <xsl:template match="entry">
        <xsl:copy>
            <xsl:for-each-group select="node()" group-starting-with="span[@style = 'bold'][matches(., '^[0-9]+\.$')]">
                <xsl:choose>
                    <xsl:when test="self::span[@style = 'bold'][matches(., '^[0-9]+\.$')]">
                        <sense nr="{replace(., '[^0-9]+', '')}">
                            <xsl:apply-templates select="current-group() except ."/>
                        </sense>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:apply-templates select="current-group()"/>
                    </xsl:otherwise>
                </xsl:choose>
            </xsl:for-each-group>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>

producing the output

<?xml version="1.0" encoding="UTF-8"?>
<dict>
    <entry>
        <form>word</form>
        <gram>noun</gram>
        <sense nr="1">
        <def>this is a definition in the first sense.</def> – <cit type="example">
            <quote>This is a <span style="bold">quote</span> for the first sense. </quote>
        </cit>
        </sense>
        <sense nr="2">
        <def>This is a definition for the second sense</def> – <cit type="example">
            <quote>This is a quote for the second sense.</quote>
        </cit>
    </sense>
    </entry>    
</dict>

Thanks, Martin! This is great. – Tench Feb 11 '17 at 07:02 — Tench, Feb 11 '17 at 07:02
