----------------------------------
Description:
despite [XPath API
spec|https://docs.oracle.com/javase/8/docs/api/javax/xml/xpath/XPathExpression.html#evaluate-java.lang.Object-javax.xml.namespace.QName-]
states:
{quote}If a null value is provided for item, an empty document will be used for
the context{quote}
saxon, starting from 9.6, they decided to ignore it and throw NPE if the node
is null, from [saxon
javadoc|https://www.saxonica.com/html/documentation9.8/javadoc/net/sf/saxon/xpath/XPathExpressionImpl.html#evaluate-java.lang.Object-javax.xml.namespace.QName-]:
{quote} Contrary to the interface specification, Saxon does not supply an empty
document when the value is null. This is because XPath 2.0 allows the context
item to be "absent" (null). So Saxon executes the XPath expression with the
context item undefined. {quote}
