Given this web.xml:

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
  version="3.1">
  <servlet>
    <servlet-name>comingsoon</servlet-name>
    <servlet-class>mysite.server.ComingSoonServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>comingsoon</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>

If you declare this settings:

"xml.references": [
  {
    "pattern": "**/web.xml",
    "expressions": [
      {
        "from": "servlet-mapping/servlet-name/text()",
        "to": "servlet/servlet-name/text()"
      }
    ]
  }
]

You shoud benefit with references for servlet-name:

The PR can be reviewed now, the code should be cleaned and I have written some tests.
