Re: problen comparing node with one variable in xslt

   <xsl:variable name="var_masterinformacion_id">
	   <xsl:value-of select= "sn_servicioproyecto/masterinformacion_sel"/>
   </xsl:variable>

In general you shouldn't do that, but instead should do

<xsl:variable name="var_masterinformacion_id"
	 select= "sn_servicioproyecto/masterinformacion_sel"/>


However that is unlikely to be your problem here.
It's not possible to say what your problem is as the code you showed:

  <xsl:for-each select="masterinformacion_padre">
  <xsl:choose>
  	<xsl:when test=".=$var_masterinformacion_id">ok</xsl:when>
  </xsl:choose>
  </xsl:for-each>

is syntactically correct but you say 

"it doesn't run."

do you mean that your system gave an error message and produced no
output, or just that you did not get the output you expect?

As always, it's best to post a _small_ complete input doc, and a _small_
complete xslt stylesheet then people can run it and comment on the
results.
