below code is used for print the radio button for route_opt is same (for both R1,R1 then radion button is one )

temp and route_opt is xsl variable
i am assiging the route_opt value to temp variable but it is not changing outside the when condition. but it is change in when condition how it is possible ???.if any way how to assign ????
consider route_opt contains
route_opt contains R1,R1,R2,R2 and changes continously resepctively.
1st and second time (in detail2) loop time temp and route_opt is same but 3rd time it is not same then goes to otherwise condition in that change value and newly assign route_opt value to temp variable and it is assign but outside it is not change for 4th time.

<xsl:variable name="temp"><xsl:value-of select="//Detail2/route_opt"/></xsl:variable>
<xsl:for-each select ="//Detail2">
<xsl:variable name="route_opt"><xsl:value-of select="route_opt"/></xsl:variable>
<xsl:choose>
<xsl:when test="normalize-space($line_no)=normalize-space($line_no__tkt_chk)">
<TD id="td2_{$route_opt}" class="editDisplayClass" width="3%">
<INPUT id="selRadioId_{$route_opt}" TYPE="radio" name="Detail2.{normalize-space($line_no__grptkt)}.selected" ISCHANGED="true" value="Y" checked="false" selected="{$selected}" amount="{$amount}" grpId="{$line_no__grptkt}" net_amt="{$net_amt}" lineNo="{$line_no}" line_no__grptkt="{$line_no__grptkt}" onclick="setValues( this );" /></TD>
</xsl:when>
<xsl:otherwise>
<xsl:choose>
<xsl:when test="normalize-space($route_opt) = normalize-space($temp)">
</xsl:when>
<xsl:otherwise>
<TD id="td2_{$route_opt}" class="editDisplayClass" width="3%">
<INPUT id="selRadioId_{$route_opt}" TYPE="radio" name="Detail2.{normalize-space($line_no__grptkt)}.selected" ISCHANGED="true" value="Y" checked="false" selected="{$selected}" amount="{$amount}" grpId="{$line_no__grptkt}" net_amt="{$net_amt}" lineNo="{$line_no}" line_no__grptkt="{$line_no__grptkt}" onclick="setValues( this );" /></TD>
<xsl:variable name ="temp" select="normalize-space($route_opt)"/>

</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>

If you post a small but representative XML input sample and the corresponding HTML you want to create with your stylesheet then we are hopefully able to show you how to achieve that with XSLT.
Please also mention whether you use XSLT 2.0 or 1.0.

In general variables in XASLT are more lik constants, once assigned they cannot be changed. Can you show a small example of what you need without the extraneous material as I am finding it hard to understand the problem? Where for example are you trying to assign $route_opt to $temp?

As a side issue this:

Code:

<xsl:variable name="temp"><xsl:value-of select="//Detail2/route_opt"/></xsl:variable>

is normally better written as:

Code:

<xsl:variable name="temp" select="//Detail2/route_opt"/>

You haven't explained yourself very clearly (start by finding the shift key on your keyboard, a few capital letters can help a lot, whereas multiple question marks help very little). I think you've almost certainly not understood that XSLT is a declarative, function language and not a procedural one, and that it needs a different approach if your previous experience is with procedural languages. It's worth standing back and explaining your requirements, rather than trying to fix your code.
