Relative newbie question:  XSLT 2.0, grouping with text nodes and
mixed text

For a newbie you've done *very* well and you could have fooled me. You had only one small oversight.

I'm trying to convert a non-XML dictionary into XML. I've got it mostly done, but I want to input elements that currently look like ... and transform them into this ... i.e. each original <hop> element in <examples> is followed by plain text or mixed text, not containing <hop> or <examples> elements. I want to group the nodes after each <hop> element and wrap them in <eng>...</eng> tags. I tried the following, and a few other variations, but the desired <eng> element comes out an empty <eng/>

Yes, because you failed to include the text nodes in the population being grouped.

        <xsl:template match="examples">
                <examples>
                <xsl:for-each-group select="*" group-starting-with="hop">

Simply change the above to select="node()" in order to select all node children and not just element children.

Actually, there is an edge case involved because of the very first empty text node. I've added an <xsl:if> to the loop so that any content before the very first <hop> is ignored. The running example is below.

I hope this helps.
