Validating the XML – PB Docs 2021

Before you try to build a document from a file or string, you can
test whether the XML is well formed or, optionally, whether it conforms
to a DTD or Schema using the XMLParseFile or XMLParseString PowerScript
functions. For example, this code tests whether the XML in a file is
well formed:

By default, these functions display a message box if errors occur.
You can also provide a parsingerrors string argument to handle them
yourself. For more information about these functions, see the section called “XMLParseFile” in PowerScript Reference and
the section called “XMLParseString” in PowerScript Reference.
