Domain name XML

In XML creation: Part 1, I went about creating an XML document, with both a CSS and XSLT, that was used to store my video game information.

Yesterday I was going through my domains, and realized that it would be pretty helpful to have an XML document where I could store domain name information, since I've got too many to keep track of in my head.

The layout

Using lists, this the version 1 that I came up with yesterday:

• domains
  • domain
    • name
    • created
      • year
      • month
      • day
    • expires
      • year
      • month
      • day
    • registrar
    • servers
      • server
        • ip
        • path
    • subdomains
      • subdomain
        • name
        • path
        • server

Now that we've got a layout, let's create an empty structure.

Empty structure

Unlike the last time we did this, we'll use attributes much more this time.

<?xml version="1.0" encoding="UTF-8"?>
    <domains>
        <domain id="1">
            <name>jamesrskemp.net</name>
            <created year="2002" month="12" day="11"/>
            <expires year="2009" month="5" day="15"/>
            <registrar>GoDaddy</registrar>
            <servers>
                <server id="1">
                    <ip>76.12.10.196</ip>
                    <path>\Inetpub\wwwroot\jamesrskemp</path>
                </server>
            </servers>
            <subdomains>
                <subdomain id="1" name="www" server="1">
                    <path>http://jamesrskemp.com</path>
                </subdomain>
            </subdomains>
        </domain>
    </domains>

Document Type Definition (DTD)

The domain_names.dtd for the above XML is listed below.

<!ELEMENT domains (domain*)>
<!ELEMENT domain (name, created, expires, registrar, servers*, subdomains*)>
<!ATTLIST domain id CDATA #REQUIRED>
<!ELEMENT name (#PCDATA)>
<!ELEMENT created EMPTY>
<!ATTLIST created year CDATA #REQUIRED>
<!ATTLIST created month CDATA #REQUIRED>
<!ATTLIST created day CDATA #REQUIRED>
<!ELEMENT expires EMPTY>
<!ATTLIST expires year CDATA #REQUIRED>
<!ATTLIST expires month CDATA #REQUIRED>
<!ATTLIST expires day CDATA #REQUIRED>
<!ELEMENT registrar (#PCDATA)>
<!ELEMENT servers (server*)>
<!ELEMENT server (ip, path)>
<!ATTLIST server id CDATA #REQUIRED>
<!ELEMENT ip (#PCDATA)>
<!ELEMENT path (#PCDATA)>
<!ELEMENT subdomains (subdomain*)>
<!ELEMENT subdomain (path)>
<!ATTLIST subdomain id CDATA #REQUIRED>
<!ATTLIST subdomain name CDATA #REQUIRED>
<!ATTLIST subdomain server CDATA #REQUIRED>

Final XML

With the XML and DTD created, we now have a valid XML document.
