Table 4 Boolean Methods
|
|---|
The boolean method converts the value of object1 to Boolean, and returns true
or false. |
The exists method checks whether a value is present in object1. If
a value is present, it returns Boolean true; otherwise, it returns Boolean false. |
The
false method always returns Boolean false. |
The lang method returns Boolean true if the value
of string1 matches the language of the xsl:lang element; otherwise, it returns Boolean
false. |
The not method returns Boolean true if boolean1 is false, and returns Boolean
false if boolean1 is true. Note: Boolean parameters cannot accept values with capital letters.
For example, “True” and “TRUE” are not valid Boolean values, but “true” is. |
The
true method always returns Boolean true. |
