xmllint: Validate XML against DTD schema hosted online.

xmllint

$ xmllint --dtdvalid ${URL} ${source_file-xml}

try on your machine

The command "xmllint --dtdvalid ${URL} ${source_file-xml}" is used to validate an XML file against a specified DTD (Document Type Definition) using the xmllint tool.

Let's break down the command:

"xmllint": This is the name of the command-line tool used for parsing and validating XML documents.
"--dtdvalid ${URL}": This option specifies the URL of the DTD file to be used for validation. The ${URL} is a placeholder for the actual URL.
"${source_file-xml}": This parameter represents the path or filename of the XML file that needs to be validated. The ${source_file-xml} is a placeholder for the actual file name. If not provided, it assumes a default value of "xml".

Overall, the command is telling xmllint to validate the XML file specified by ${source_file-xml} against the DTD file located at ${URL}. This can help identify any potential issues or errors in the XML file's structure or adherence to the rules defined in the DTD.
