My question is related to: XSLT with overlapping elements? – but the proposed solution is not working for me.
Input
I have some TEI-XML encoded like this:
<delSpan spanTo="#abcbb6b8-b7bd-4b96-93c1-0a34500e12c0"/>
<lg>
<l>some text that is deleted</l>
</lg>
<lg>
<l>much more text</l>
<l>another line of text</l>
</lg>
<anchor xml:id="abcbb6b8-b7bd-4b96-93c1-0a34500e12c0"/>
I want to process it with XSL and my output should look like:
<div class="delSpan">
<div class="lg">
<span>some text that is deleted</span>
</div>
<div class="lg">
<span>much more text</span>
<span>another line of text</span>
</div>
</div>
XSLT At the moment I am trying to work with the following templates:
<xsl:template match="tei:delSpan">
<xsl:variable name="id">
<xsl:value-of select="substring-after(@spanTo, '#')"/>
</xsl:variable>
<xsl:for-each-group select="*" group-ending-with="tei:anchor[@xml:id=$id]">
<div class="delSpan">
<xsl:apply-templates />
</div>
</xsl:for-each-group>
</xsl:template>
<xsl:template match="tei:lg">
<div class="lg">
<xsl:apply-templates/>
</div>
</xsl:template>
<xsl:template match="tei:l">
<span>
<xsl:apply-templates/>
</span>
</xsl:template>
But this just produces the following output:
<div class="lg">
<span>some text that is deleted</span>
</div>
<div class="lg">
<span>much more text</span>
<span>another line of text</span>
</div>
So I am asking myself if there is any common and easy solution to deal with so called milestone-elements and process like described above?
If you move the for-each-group to the parent element of any delSpan (or any element you expect to apply the wrapping to) then it would look like
<xsl:template match="*[delSpan]">
<xsl:for-each-group select="*" group-starting-with="delSpan">
<xsl:choose>
<xsl:when test="self::delSpan">
<xsl:variable name="id-ref" select="substring(@spanTo, 2)"/>
<div class="{local-name()}">
<xsl:for-each-group select="current-group() except ." group-ending-with="id($id-ref)">
<xsl:choose>
<xsl:when test="current-group()[last()] is id($id-ref)">
<xsl:apply-templates select="current-group()[not(position() = last())]"/>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</div>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:template>
