Is it possible to transform from:

<root>
<element>
<info>
<name>Name</name>
</info>
<links>
<child>A</child>
<child>B</child>
<child>C</child>
<child>D</child>
</links>
</element>
</root>

to the following form?

<td onclick="function(A,B,C,D)">Name</td>

Where it doesn't necessarily have to have 4 children (i.e. could have any variable number of children).

Thank you so much!

Sure. Assuming <element> is the context node:

In XSLT 2.0:

<td onclick="function({string-join(links/*, ','})">
  <xsl:value-of select="info/name"/>
</td>

In XSLT 1.0:

<td>
  <xsl:attribute name="onclick">
    <xsl:text>function(</xsl:text>
    <xsl:for-each select="links/*">
      <xsl:value-of select="."/>
      <xsl:if test="position()!=last()">,</xsl:if>
    </xsl:for-each>
    <xsl:text>)</xsl:text>
  </xsl:attribute>
  <xsl:value-of select="info/name"/>
</td>
