xslt send variable to another template -

i have xml example this:

<p class="exer_header" style="display: none;">            <image-input size="5" value="val1" /> </p> <p class="exer_header" style="display: none;">            <image-input size="5" value="val2" /> </p> <answers-img>     <answer-img class="imagednd_answer1" value="val1"/>     <answer-img class="imagednd_answer2" value="val2"/> </answers-img> 

and xslt ex. here:

<xsl:template match="image-input">     <xsl:variable name="id" select="generate-id(.)"/>     <xsl:element name="input">         <xsl:attribute name="id"><xsl:value-of select="$id"/></xsl:attribute>         <xsl:attribute name="class">exer_input</xsl:attribute>     </xsl:element> </xsl:template> <xsl:template match="answers-img">        <xsl:for-each select="//image-input">              <xsl:element name="div">                 <xsl:element name="input">                     <xsl:attribute name="class">ans_img_input</xsl:attribute>                     <xsl:attribute name="type">hidden</xsl:attribute>                     <xsl:attribute name="value">***{id}***</xsl:attribute>             </xsl:element>                  <xsl:apply-templates select="//answers-img/answer-img"/>                             </xsl:element>        </xsl:for-each> </xsl:template> 

question next, how can send variable id "input" template "answers-img" template , change {id}?

upd: in "answer-img" need same id's generates in "input-img". first xslt generate code "input-img"(twice) , when somewhere templates, not in "input-img", call template "answer-img". maybe can create global array variable?

use xsl:with-param

i don't know want call template can done this:

<xsl:call-template name="answers-img"><xsl:with-param name="id" select="$id" /></xsl:call-template> 

you must add calling template:

<xsl:param name="id" />
