 Posted: Tue Sep 06, 2005 5:23 pm Post subject: [RvXML] How to save several documents in one XML file |
 |
|
| Code: | uses RichViewXML, RVXMLBase;
RichView1, RichView2 - trichviews to load/save.
RichViewXML1 - trichviewxml.
This example saves and loads two documents in 'd:\1.xml'
// Saving
procedure TForm1.Button1Click(Sender: TObject);
var
T: TXMLTree;
MainRoot, DocRoot: TXMLTag;
begin
T := TXMLTree.Create(RichViewXML1.Encoding);
try
T.BaseFilePath := RichViewXML1.BaseFilePath;
T.Items.AddTag(RichViewXML1.RootElement, T, T);
MainRoot := T.Items[0];
MainRoot.Items.AddTag('document1', T.Items[0], T);
DocRoot := MainRoot.Items[MainRoot.Items.Count-1];
RichViewXML1.RichView := RichView1;
RichViewXML1.SaveToXML(DocRoot);
MainRoot.Items.AddTag('document2', T.Items[0], T);
DocRoot := MainRoot.Items[MainRoot.Items.Count-1];
RichViewXML1.RichView := RichView2;
RichViewXML1.SaveToXML(DocRoot);
T.SaveToFile('d:\1.xml', RichViewXML1.WantTabs);
finally
T.Free;
end;
end;
// Loading
procedure TForm1.Button2Click(Sender: TObject);
var
T: TXMLTree;
MainRoot, DocRoot: TXMLTag;
begin
T := TXMLTree.Create(RichViewXML1.Encoding);
try
T.BaseFilePath := RichViewXML1.BaseFilePath;
T.UnicodeTags.Add('utext');
T.LoadFromFile('d:\1.xml');
RichViewXML1.RichView := RichView1;
MainRoot := T.Items.FindTagOfName(RichViewXML1.RootElement);
if MainRoot<>nil then begin
DocRoot := MainRoot.Items.FindTagOfName('document1');
if DocRoot<>nil then
RichViewXML1.LoadFromXML(DocRoot);
RichViewXML1.RichView := RichView2;
DocRoot := MainRoot.Items.FindTagOfName('document2');
if DocRoot<>nil then
RichViewXML1.LoadFromXML(DocRoot);
end;
finally
T.Free;
end;
RichView1.Format;
RichView2.Format;
end; |

RVXML.SaveToStream saves absolutely the same information in stream as RVXML.SaveToFile saves to file.
As for XML vs RVF... Generally, RichViewXML's XML and RVF data contain the same information. XML has an advantage that it can be understanded by human, RVF is a computer-oriented format and may contain binary data (if rvfoSaveBinary is excluded from RVFOptions, binary data are saved as hexadecimal numbers, so it still cannot be read by humans). Binary RVF files are usually smaller than the corresponding XML, non-binary may be larger in some cases.
The main disadvantage of RichViewXML - it was not created by me and I can give no guaranties about it quality (I continue to support it, though). All new TRichView features are added to RVF immediately, RichViewXML updates follow with some delay. |

RvXML.SaveToFile('c:\doc.xml') saves TRichView (or TRichViewEdit) assigned to RvXML.RichView.
RichViewXML has documentation as a demo project (documentation in XML files, a viewer is included) |
