Filling tables with XML data

Question

Hi!!
I need help with this!! I don't know the right way to implement such a problem!
Here is the scenario:
I do have a number of tables (relations) created in MS Access and I do have an XML document now what I'm looking for is to fill these tables with data from the XML document!
Here are the tables that I have (IDs are auto numbered fields)
Table Name: datee
Fields:
1- datee_ID
2- datee_day
3- datee_month
4- datee_year
Table Name: paragraph
Fields:
1- paragraph_ID
2- paragraph_String
Table Name: month
Fields:
1- month_ID
2- month_String
Table Name: notee
Fields:
1- notee_ID
2- notee_to
3- notee_from
4- notee_heading
5- notee_datee_day
6- notee_datee_month
7- notee_datee_year
Table Name: year
Fields:
1- year_ID
2- year_String
Table Name: day
Fields:
1- day_ID
2- day_String
Table Name: to
Fields:
1- to_ID
2- to_String
Table Name: from
Fields:
1- from_ID
2- from_String
Table Name: heading
Fields:
1- heading_ID
2- heading_String
Table Name: notee_paragraph
Fields:
1- notee_paragraph_ID
2- notee_ParentID
3- notee_paragraph_String
Here is the XML document
<notee>
<to>Jane</to>
<from>Tom</from>
<heading>Reminder</heading>
<paragraph>Hi</paragraph>
<paragraph>Don�t be late!</paragraph>
<datee>
<day>13</day>
<month>May</month>
<year>2004</year>
</datee>
<to>Mark</to>
<from>Ed</from>
<heading>Invitation</heading>
<paragraph>Hello</paragraph>
<paragraph>Please come</paragraph>
<paragraph>Take care</paragraph>
<datee>
<day>14</day>
<month>March</month>
<year>2004</year>
</datee>
</notee>
I used DOM to parse the XML document but my only problem is in finding an algorithm that I should follow to fill in these tables!! so HOW!! I'm a bit confused??
Any help or advice will be highly appreciated!

Answer 1

For each of your elements, build a class representing the object. All your classes should have a method
to create an instance of the class from an XML node (i.e. public static Object fromXML(Node)), and also
a 'full constructor' (with parameters for all members of the class.
Then, build utility classes to hold the table access.
Short example for table DATEE:
public class Datee {
   private int id;
   private byte day, month, year;
   public Datee(int id, byte day, byte month, byte year) {
      this.id = id;
      this.day = day;
      this.month = month;
      this.year = year;
   public static Object fromXML(Node node) {
      NamedNodeMap attributes = node.getAttributes();
      String strid = attributes.getNamedItem("id").getNodeValue();
      String strday = attributes.getNamedItem("day").getNodeValue();
      String strmonth = attributes.getNamedItem("month").getNodeValue();
      String stryear = attributes.getNamedItem("year").getNodeValue();
      try {
         id = Integer.parseInt(strid);
         day = Integer.parseInt(strday);
         month = Integer.parseInt(strmonth);
         year = Integer.parseInt(stryear);
      catch(Exception e) {
      return new Datee(id, day, month, year);
}Its of course the simplest example. If instance contains other object instances, just use its fromXML() method to create it.
Hope this helped,
Regards.
