Frage

I would like to sum some values using XSLt V 1.0 but they are treated as strings. A sample of the xml is below as is my sample xslt. Should I change the data type in the underlying SQL view? I have tried various number data types but I need to retain the decimal or money format as this is supposed to be a total of dollars. Is there a way of using perhaps a variable in XSLT that will allow me to cast this string as a number? I have tried to convert using number() but I still get NaN. Don't know too much about xslt and would be very grateful for any help or if you can point me to relevant resource.

     <?xml version="1.0" encoding="utf-8"?>
    <xml>
      <object>
        <objectid>183382</objectid>
        <objectnumber>Test00001237</objectnumber>

          <lcc>
            <groupname>Costs: Acquisition planning</groupname>

War es hilfreich?

Lösung

I need to retain the decimal or money format as this is supposed to be a total of dollars.

In general, it's best for input data that needs to be treated numerically to contain only digits, decimal point and minus sign. You can always reformat the result as decimal/currency at the output. If you are unsure about the currency used, include it in a separate element or as an attribute.
