number function in XPATH1.0 and decimal type in xml schema

kssudhish · February 20th, 2009, 07:40 AM

Hi,

We are using XSLT1.0.
Our inbound SOAP request contains a decimal type element, which is sometimes populated with a + sign. According to W3 specifications '+' sign is valid. But as per XPATH1.0 specification, number () doesn't support a '+' sign. It returns an 'NaN'.

It appears like there is a gap between these two specifications. Is there any workaround to this issue? or am i missing something?

Any help in this regard is greatly appreciated.

Thanks,
Sudhish

XPath 1.0 only has support for one number data type which is a double data type. As for using that decimal type, if the '+' sign is all that is different you could strip it e.g.
number(translate(foo, '+', ''))
(where foo is the element containing the decimal number).

You can solve the problem by moving forward to XSLT 2.0 / XPath 2.0, or by manually stripping off the "+" sign.
