xml - How do I use an xdoxslt variable inside xsl code, in BI Publisher? -

-

i trying create loop increments variable, use variable inside of xsl code. here code using increment counter:

<?xdoxslt:set_variable($_xdoctx, ‘counter’, 0)?>  <?for-each-group:$g2;./status?> <?sort:current-group()/status;'ascending';data-type='text'?> <?xdoxslt:set_variable($_xdoctx, ‘counter’, xdoxslt:get_variable($_xdoctx, ‘counter’)     + count(xdoxslt:distinct_values(current-group()/action)))?> <?end for-each-group?>

the following code output number need:

<xsl:value-of select="xdoxslt:get_variable($_xdoctx, ‘counter’)"/>

so know loop working , variable has correct number. however, need use variable in following code:

<xsl:attribute name="number-rows-spanned"  xdofo:ctx="block"> <xsl:value-of select="xdoxslt:get_variable($_xdoctx, ‘counter’)"/> </xsl:attribute>

when use code following error:

java.lang.numberformatexception: input string: ""

i have tried:

<xsl:variable name="rowcount" select="xdoxslt:get_variable($_xdoctx, ‘counter’)"/> <xsl:attribute name="number-rows-spanned"  xdofo:ctx="block"> <xsl:value-of select="$rowcount"/> </xsl:attribute>

this results in same error. there workaround allow me use variable in way or should find alternate solution?

this report trying create:

group column1      group column2          column3    | column4    | column5   | column6         group left | group left | group left | number      end group column2     totals          column3    | column4    | column5   | column6         group left | group left | group left | sum()  end group column1

the problem in "totals" table, column6 values being split when there more 1 column2 in grouping.

i found workaround, prefer more elegant solution @ least works. did made last column "ghost" column (no field , no borders). inserted table 2 columns column5. tags placed before , after table. in table put value column5, , sum needed in column6. it's not perfect, there small formatting issues. prefer better solution, if has suggestions.
