How to use the body-parser.xml function in body-parser

// Make sure that each request has the "parsedUrl" parameter
		this.app.use((req: express.Request, res: express.Response, next: express.NextFunction) => {
			(req as ICustomRequest).parsedUrl = parseUrl(req);
			next();
		});

		// Support application/json type post data
		this.app.use(bodyParser.json({ limit: "16mb", verify: (req, res, buf) => {
			// @ts-ignore
			req.rawBody = buf;
		}}));

		// Support application/xml type post data
		// @ts-ignore
		this.app.use(bodyParser.xml({ limit: "16mb", xmlParseOptions: {
			normalize: true,     // Trim whitespace inside text nodes
			normalizeTags: true, // Transform tags to lowercase
			explicitArray: false // Only put properties in array if length > 1
		  } }));

		// Make sure that Vue history mode works properly
		this.app.use(history({
			rewrites: [
				{
					from: new RegExp(`^\/(rest|healthz|css|js|${this.endpointWebhook}|${this.endpointWebhookTest})\/?.*$`),
					to: (context) => {
						return context.parsedUrl!.pathname!.toString();
					}
				}
			]
		}));
