copied!<p>You can start by looking at Delphi's TXMLDocument component. This will provide you with the basics of working with XML/DOM. It's simple and can be added by dropping it onto your Form. It has LoadFromFile and SaveToFile methods and is easily navigated.</p> <p>However, at some point you will exhaust TXMLDocument's features, especially if you want to work with things like XPath.</p> <p>I suggest you look at IXMLDOMDocument2 which is part of MSXML2_TLB, e.g.</p> <pre><code> XML := CreateOleObject('MSXML2.DOMDocument.3.0') as IXMLDOMDocument2; XML.async := false; XML.SetProperty('SelectionLanguage','XPath'); </code></pre> <p>You will need to add msxmldom, xmldom, XMLIntf, XMLDoc & MSXML2_TLB to your uses section.</p> <p>There are a few component libraries out there but I would suggest writing your own helper class or functions. Here's an example of one we wrote and use:</p> <pre><code>function XMLCreateRoot(var xml: IXMLDOMDocument2; RootName: string; xsl: string = ''; encoding: string = 'ISO-8859-1'; language: string = 'XPath'): IXMLDOMNode; var NewPI: IXMLDOMProcessingInstruction; begin if language<>'' then xml.SetProperty('SelectionLanguage','XPath'); if encoding<>'' then begin NewPI:=xml.createProcessingInstruction('xml', 'version="1.0" encoding="'+encoding+'"'); xml.appendChild(NewPI); end; if xsl<>'' then begin NewPI:=xml.createProcessingInstruction('xml-stylesheet','type="text/xsl" href="'+xsl+'"'); xml.appendChild(NewPI) end; xml.async := false; xml.documentElement:=xml.createElement(RootName); Result:=xml.documentElement; end; </code></pre> <p>Take it from there.</p>
