How to multiply 2 sequences ?
Hello XSLT users, I am developing an XML, XSLT 2.0 based food database. I am trying to extract and process the XML data but until now with limited success. The database has the following xml schema: some of the single food ingredients ( extracted via attribute id ) <xs:element name="NAME" type="xs:normalizedString"> <xs:annotation xml:lang="de"> <xs:documentation>Bezeichnung des Lebensmittels</xs:documentation> </xs:annotation> </xs:element> <xs:element name="GCAL" type="xs:nonNegativeInteger"> <xs:annotation xml:lang="de"> <xs:documentation>Energie, kcal/100g</xs:documentation> </xs:annotation> </xs:element> all single food ingredients collected in food element "ing" having attribute id The following issues need to be solved : 1. extraction of single food ingredients <xsl:template match="/"> <xsl:variable name="input_bls" as="item()*"> <xsl:sequence select="('B100000', 'B105100', 'B106311')"/> </xsl:variable> <xsl:variable name="input_amt" as="item()*"> <xsl:sequence select="(100, 50, 10)"/> </xsl:variable> <xsl:apply-templates select="in:ingredient/in:ing[@in:id=$input_bls]"/> </xsl:template> this works 2. multiplication with weight factor variable $input_amt <xsl:template match="in:ingredient/in:ing"> <xsl:param name="input_amt">0</xsl:param> <xsl:variable name="GCAL" select="in:GCAL * $input_amt"/> </xsl:template> this works with the same weight factor for every food element, but the weight factors are different for every food element 3. sum of single food ingredients per food element this is also unclear because step 2 is still unclear. Can You assist me with this ? How can I multiply a node sequence with different factors ? best regards Peter Teichert This e-mail is intended only for the above addressee.
