sum() on search criteria

2003-02-20 07:23:35

Is it possible to perform a search using XSL/XSLT on a XML file that has attribute's and then perform a sum only only on the search criteria for example: Sorry about all the quotes " " but hotmail try's to turn it into a web page (pain)

"<td><strong>Total cost</strong></td>"

  "<!-- I commented out because it returns multiple sum's-->"
  "<!--<xsl:for-each select="//INVOICE/LINEIT[(_at_)ACCNO=100]">-->"

  "<!-- this works but sum's all the PRICE atribute's-->     "
  " <td><xsl:value-of select="sum(//INVOICE/LINEITEM/@PRICE)"/></td>"
" <!--</xsl:for-each>-->"
