xmlIsValidObject

Test the existence of a XML object

Calling Sequence

exists = xmlIsValidObject(obj)

Arguments

obj

a XML object or a matrix of strings containing the variables names

exists

a boolean or a matrix of booleans to indicate if the XML objects exist or not

Description

When a XML document has been deleted all the attached objects are destroyed, but on the Scilab side the objects are still alive. So this function is useful to know if an object on the Scilab side is valid or not.

Examples

doc = xmlRead("http://www.w3.org/TR/2009/REC-xml-names-20091208/xml-names-10-3e.xml");
r = doc.root
// must return %T
xmlIsValidObject(r)

// We delete the doc
xmlDelete(doc);

// must return [%F %F]
xmlIsValidObject(["doc" "r"])
