html - XSLT Assign Function Return Value to Variable -

i can generate id way:

<td id= "{generate-id(@value)}">  </td> 

however, want assign variable , use variable. so, tried that:

<xsl:variable name="value_holder" select="{generate-id(@value)}" /> <td id= "{$value_holder}">  </td> 

however xslt doesn't work due line:

<xsl:variable name="value_holder" select="{generate-id(@value)}" /> 

how can store variable , use inside html element?

this has solved it:

<xsl:variable name="value_holder" select="generate-id(@value)" /> <td id= "{$value_holder}">  </td>
