Choose File | Close All from the file menu to be sure that you have completely closed the package you just finished installing. Now create a new application and drop down a TButton, TMemo and TListBox on a Delphi form.
Drop down both a TXmlToDomParser object and a TDomImplementation object on your form. You can, needless to say, find both of these objects on the XML page that you just created. Now you need to link these two components together so they can work with one another. To do this use the mouse to set the DomImpl property of the TXmlToDomParser to the TDomImplementation object that resides on your form.
Create an OnClick handler for your button and enter the following lines of code in it:
procedure TForm1.Run1Click(Sender: TObject);
var
Doc: TDOMDocument;
List: TDomNodeList;
Len, i: Integer;
S: string;
begin
Memo1.Clear;
ListBox1.Items.Clear;
Doc := XmlToDomParser1.FileToDom(GetStartDir + 'sam1.html');
Len := DomImplementation1.documents.Length;
for i := 0 to Len - 1 do begin
S := DomImplementation1.Documents.Item(i).ChildNodes.Item(i).Code;
Memo1.Lines.Add(S);
end;
List := Doc.DocumentElement.GetElementsByTagName('CD');
for i := 0 To List.length -1 do
ListBox1.Items.Add(List.item(i).Code);
end;
This code uses both of the components you just installed to iterate through an XML file and display its contents. The code actually parses the code in two different ways, both of which should be of some interest to readers of this document. The two examples I've chosen will hopefully act as starting points from which you can branch out into a more detailed exploration of this technology.
In the third line, you retrieve an instance of the TDomDocument class from TXmlToDomParser component. Needless to say, TDomDocument represents an entire XML document. I use the TXmlToDomParser component that you just installed to load an XML file. Here is a sample of a very simple XML file you can work with if you want:
<HTML>
<HEAD>
<TITLE>Sample XML File</TITLE>
</HEAD>
<BODY>
<P>Right under this line I insert an XML data island.</P>
<XML ID="CDXML">
<CDS>
<CD>Two Against Nature</CD>
<CD>Giant Steps</CD>
<CD>Round About Midnight</CD>
<CD>Imaginary Day</CD>
</CDS>
</XML>
</BODY>
</HTML>
Just save this file to disk as Sam1.xml or Sam1.html. Then you can load it into the document you just created by writing something like this:
Doc := XmlToDomParser1.FileToDom('c:\temp\sam1.xml');
Of course, on your system, there might be a different path to the file than the one I show here.
The next thing you want to find out is how many nodes there are at the top level of your document. The nodes of the document are arranged hierarchically, so that as you dig into the document you find nodes buried within nodes. For instance, the <CD> node is buried within the <CDS> node. But at first, all we want is the top level nodes. To get them, write the following line of code:
Len := DomImplementation1.documents.Length;
Now you want to iterate through these nodes and see what is in them. To get at the content of the nodes, write the following code:
var
S: string;
begin
... // Code ommitted heren
for i := 0 to Len - 1 do begin
S := DomImplementation1.Documents.Item(i).ChildNodes.Item(i).Code;
Memo1.Lines.Add(S);
end;
... // Code ommitted here.
end;
I've changed the code slightly here from the version I showed you earlier in this paper. The change was implemented to make the code easier for you to read.
The output from this part of the program should look something like this:
<HEAD>
<TITLE>Sample XML File</TITLE>
</HEAD>
<BODY>
<P>Right under this line I insert an XML data island.</P>
<XML ID="CDXML">
<CDS>
<CD>Two Against Nature</CD>
<CD>Giant Steps</CD>
<CD>Round About Midnight</CD>
<CD>Imaginary Day</CD>
</CDS>
</XML>
</BODY>
