[xsl] Problem using Math functions

["Pankaj Bishnoi" <pankaj.bishnoi@xxxxxxxxxxx>]

Hi
    I am facing problem in math function '+'.  My Source XML is :::

<employees>
    <employee>
         <Arg1>1000020000300004000050000</Arg1>
         <Arg2>0000000000000001000010000</Arg2>
    </employee>
</employees>

and  XSL is ::::

     <xsl:template match="/">
      <employees>
        <employee>
          <Output>
          <xsl:value-of select="/employees/employee/Arg1+
/employees/employee/Arg2"/>
          </Output>
         </employee>
          </employees>
     </xsl:template>

Now the Output generated is ::::


<employees>
<employee>
 <Output>1000020000300005000000000</Output>
</employee>
</employees>



Now here the output generated is 1000020000300005000000000 it should have
been 1000020000300005000060000.   I am using Xalan transformer for my
transformations. Here the transformer is appending five 0's in the last 5
positions. whenever the ouput exceeds 20 characters then it inserts 0's.

Anybody having any idea on this problem??

Please advise. Thanks in advance.

Thanks
Pankaj
