QUESTION
I have an issue with jsel, a library which uses xPath expressions to evaluate data. I am trying to validate this expression: '//Pregnancy != true()' against a data object and I always have false as my result. For example the expression '//Sex != "f"' works perfect. I am using a custom schema for the jsel dom object. The question is why doesn't '//Pregnancy != true()' never returns true if Pregnancy is 'false' or false or null?
...ANSWER
Answered 2021-Dec-09 at 11:40In XPath 1.0, //Pregnancy != true()
is comparing a node-set to a boolean, and the rules for that comparison are that it means boolean(//Pregnancy) != true()
, which is true only if there are no Pregnancy elements in the document.
I don't actually know how JSEL maps your Javascript objects to XML, but I would imagine that using the string "true"
is more reliable than using the boolean true()
.
You also need to be aware that in XPath, //Sex != "f"
is true if there is a Sex
element whose value is not "f". It's more likely that you want not(//Sex = "f")
which is true if there is no Sex
element whose value is "f".

Install jsel
You can use jsel like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jsel component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
