Here are the steps to use xml-model processing instructions in the XML R package to link an .xsd schema with XML:
.packages("XML")
(XML)
Create XML file: Create a new XML file or use an existing XML file.
Create an "xml-model" processing instruction: In the XML file, create an "xml-model" processing instruction using the following syntax:
<?xml-model href="path-to-schema.xsd" type="application/xml" schematypens="http://www.w3.org/2001/XMLSchema"?>
Replace "path-to-schema.xsd" with the actual path to the .xsd schema file. This processing instruction tells the XML parser where to find the .xsd schema file.
<- xmlTreeParse("path-to-xml-file.xml")
<- xmlValidate(xml)
This function returns a list of validation errors. If the XML file is valid, the list should be empty.
That’s how you can use xml-model processing instructions in the XML R package to link an .xsd schema with XML.
