testing 1st child

Any suggestions would be appreciated 

I have some numbered steps that may have several children in any order
but I only want to test the first child of the step

If it is a figure, warning, caution, or note do one thing if it is a
title or a para do something else

I tried the following with mixed results

<xsl:when
test="child::figure|child::table|child::warning|child::caution|child::no
te">

Sample xml :

<step1>
<note>
<para>blah blah</para>
</note>
<para>xxxxx</para>
</step1>

<step1>
<warning><para>xjsdkfjsjfs;jfa</para></warning>
<para>xxxxx</para>
</step1>

<step1>
<para>xxxxx</para>
<figure><graphic/></figure>
</step1>

<step1>
<figure><graphic/></figure>
<note>
<para>blah blah</para>
</note>
<para>xxxxx</para>
</step1>
