I am under the impression that you omit a part. Is this what you are trying?

<xsl:if test="somecondition">
   <sometag>  <!-- open the tag -->
</xsl:if>

...

<xsl:if test="somecondition">
  </sometag>   <!-- close the tag -->
</xsl:if>


Which is impossible to do, as you pointed out: it is not XML. And XSLT 
must be XML in the first place. It seems that you are trying to instruct 
the processor HOW something must be achieved. This is not what you 
should try. Just tell the processor WHAT you want it to output by what 
RULES (check out www.w3schools.com for a basic tutorial on this 
principle, or any xslt book).

We will need to see more of your code, or better, of what you want to 
output, because this is too little information. Something I can think of:

<xsl:template match="somematch">
  <xsl:choose>
  <xsl:when test="$a != $times" >
      <xsl:apply-templates select="somechild" mode="create-orOp" />
  </xsl:when>
  <xsl:otherwise>
     <xsl:apply-templates select="somechild" />
  <xsl:otherwise>
  <xsl:choose>
</xsl:template>

<xsl:template match="somechild"  mode="create-orOp">
   <xqx:orOp>
       <xqx:firstOperand>
            <xsl:apply-templates select="self::somechild" />
       </xqx:firstOperand>
   </xqx:orOp>
</xsl:template>

<xsl:template match="somechild">
   ... do something ...
</xsl:template>

The above code is one way to include/exclude the orOp + firstOperand as 
parents from some output. But it is likely not the best way, and I can 
think of many scenario's where the same is possible without the 
xsl:choose. But that depends on what you actually are trying to achieve.
