How can I disable DTD references during XML parsing in Java?

Ignoring DTD References in Document Parsing

When parsing XML files with DTD references, one may encounter errors due to missing or inaccessible DTD files. To bypass these errors while ignoring DTD references, modifications to the DocumentBuilderFactory settings are necessary.

Within the getDoc() method, instantiate a DocumentBuilderFactory and configure its features as follows:

<code class="java">DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

// Ignore DTD references
dbf.setValidating(false);
dbf.setFeature("http://xml.org/sax/features/validation", false);
dbf.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
dbf.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);

// Additional settings
dbf.setNamespaceAware(true);
dbf.setFeature("http://xml.org/sax/features/namespaces", false);

DocumentBuilder db = dbf.newDocumentBuilder();
...</code>

By disabling validation and suppressing the loading of external DTDs, the DocumentBuilder will skip DTD references during parsing. This allows the processing of XML files without relying on the availability of DTDs.

Refer to the Xerces2 documentation for additional details on customization options specific to the parser implementation.
