Remove namespace from XML in Java

Question

I want to remove namespace from XML in Java. Can you pls guide on what needs to be done. Can use DOM parser but that would be a node by node parsing. I want to know if there

Answer 1

Regex can be used for more information refer this

public static string RemoveAllXmlNamespace(string xmlData)
        {
            string xmlnsPattern = "\\s+xmlns\\s*(:\\w)?\\s*=\\s*\\\"(?[^\\\"]*)\\\"";
            MatchCollection matchCol = Regex.Matches(xmlData, xmlnsPattern);

            foreach (Match m in matchCol)
            {
                xmlData = xmlData.Replace(m.ToString(), "");
            }
            return xmlData;
        }
   }

You can find a similar example here

Regex can be painful. you can also use this api (dom) to get rid of all namespaces.refer this

 import org.w3c.dom.Document;
    import org.w3c.dom.Node;
    import org.w3c.dom.NodeList;

    ...

    /**
     * Recursively renames the namespace of a node.
     * @param node the starting node.
     * @param namespace the new namespace. Supplying null removes the namespace.
     */
    public static void renameNamespaceRecursive(Node node, String namespace) {
        Document document = node.getOwnerDocument();
        if (node.getNodeType() == Node.ELEMENT_NODE) {
            document.renameNode(node, namespace, node.getNodeName());
        }
        NodeList list = node.getChildNodes();
        for (int i = 0; i < list.getLength(); ++i) {
            renameNamespaceRecursive(list.item(i), namespace);
        }
    }
