The function should use the argument and thus read:

| function myFunction(id) {
|   var x = document.getElementById(id);
|   if (x.style.display == 'none') {
|     x.style.display = 'block';
|   } else
|   {
|     x.style.display = 'none';
|   }
| }

| <xsl:template match="dictScrap">
|   <p><xsl:apply-templates/></p>
|   <button onclick="myFunction({generate-id(following-sibling::hom)});return false;">Show related words</button>
| </xsl:template>
| <xsl:template match="hom">
|     <div id="{generate-id()}" style="display: none"><xsl:apply-templates/></div>
| </xsl:template>

The first template assumes that there is only one <hom> and the <hom>
is a sibling of the <dictScrap>. You might need to adjust that. The
important part is the use of generate-id(): If you call it with the
same node, it generates the same value.
