XML viewer

XML viewer

Postby Antonio Linares » Wed Feb 27, 2013 3:44 pm

Now that we have started a way to easy retrieve all the items inside a XML file, now we can build a GUI viewer:

viewtopic.php?f=3&t=25741

xmltree.prg
Code: Select all  Expand view
#include "FiveWin.ch"
#include "Splitter.ch"

static oSplit1, oSplit2, oLbxDatas, oLbxMethods

//----------------------------------------------------------------------------//

function Main()

   local oWnd

   DEFINE WINDOW oWnd TITLE "XML viewer" ;
      MENU BuildMenu()

   ACTIVATE WINDOW oWnd ;
      ON INIT BuildTree( oWnd ) ;
      ON RESIZE ( If( oSplit1 != nil, oSplit1:AdjLeft(),),;
                  If( oSplit2 != nil, oSplit2:AdjRight(),) )

return nil

//----------------------------------------------------------------------------//

function BuildMenu()

   local oMenu

   MENU oMenu
      MENUITEM "About" ACTION MsgAbout( "XML Viewer", "FiveTech Software" )
   ENDMENU

return oMenu

//----------------------------------------------------------------------------//

function BuildTree( oWnd )

   local oTree := TTreeView():New( 0, 0, oWnd )
   local oClass, cData, cMethod
   local hFile, oXmlDoc, oXmlIter, oTagActual
   local oTagLast, aRoots := {}

   oTree:nWidth = 180
   // oTree:SetImageList( oImageList )

   oTree:Expand()

   @ 0, 186 LISTBOX oLbxDatas VAR cData ITEMS { "one", "two", "three" } ;
      SIZE 200, 200 PIXEL OF oWnd

      // aRoots[ oTagActual:Depth() ]:Add( oTagActual:cName )
      // oRoot:Add( oTagActual:cName )
      if oTagLast != nil
         if oTagLast:Depth() < oTagActual:Depth()
            ASize( aRoots, Len( aRoots ) + 1 )
            aRoots[ oTagActual:Depth() ] = aRoots[ oTagActual:Depth() - 1 ]:Add( oTagActual:cName )
            // MsgInfo( oTagActual:cName + ", " + "open node", oTagActual:Depth() )
         endif
         if oTagLast:Depth() > oTagActual:Depth()
            aRoots[ oTagActual:Depth() - 1 ]:Add( oTagActual:cName )

      endif
      oTagLast = oTagActual
   end  
 
   // HEval( oTagActual:aAttributes, { | cKey, cValue | MsgInfo( cKey, cValue ) } )

   FClose( hFile )

   // oTree:bChanged = { || ShowClassInfo( oTree ) }

return nil

//----------------------------------------------------------------------------//

This change may be required on Harbour Class TXmlDocument, upon some types of XML files:

METHOD New( xElem, nStyle ) CLASS TXMLDocument
Code: Select all  Expand view
        IF ! Empty( ::oRoot:oChild ) .AND. ::oRoot:oChild:cName == "xml" .and. ::oRoot:oChild:cData != nil
            ::cHeader := "<=xml " + ::oRoot:oChild:cData + "?>"
         ENDIF

Antonio,
if you try my test.xml you can see it show data only on first section and not on second section
Image

or I not understood to show the records

( I thinked show all data fields as vertical)
Since from 1991/1992 ( fw for clipper Rel. 14.4 - Momos)
I use : FiveWin for Harbour November 2023 - January 2024 - Harbour 3.2.0dev (harbour_bcc770_32_20240309) - Bcc7.70 - xMate ver. 1.15.3 - PellesC - mail: silvio[dot]falconi[at]gmail[dot]com

Otto,

XML (extended markup language) is an evolution of the HTML, and is as simple as doing:

<anytag>any value</anytag>

they can be nested, without limits.

that easy :-)

Hello Antonio,
thank you. I posted the link to the PDF because I think this is a good explaination on page 3 of XML.
I use XML with FIVEWIN to exchange data for example with booking.com
Best regards,
Otto

Hi,

Is it also possible to use XML-files starting with:
Code: Select all  Expand view
<?xml version="1.0" encoding="UTF-16"?>
<MultiBlock xmlns="x-schema:ConfigFileSchema.xml">


If I read the file, the view is empty..
Regards,
Marc
