Carlos,

I don't know exactly what you mean by verify?  Do you want to ensure it is
not a null value, or if it is text or a number?

Still, here is the X-path that should give the value-of each 'test'.  I will
leave it to you to explain exactly what you mean by "verify"

<xsl:for-each select="test">
  <xsl:value-of select="."/>
  <xsl:value-of select="preceding-sibling::*[1]"/>
</xsl:for-each>

Hope that helps in some way,

Tim

PS.
you may want to use
<xsl:value-of select="preceding-sibling::*[1][self::test]"/>
to ensure that the value of the precedeing-sibling was a 'test' node
