body: <p>i need help with inno setup, i need to save some xml nodes in a specific line, but i dont know how to.</p>
  
  <p>This is my code</p>
  
  <pre><code>procedure SaveValueToXML(const AFileName, APath, AValue: string);
  var
    XMLNode: Variant;
    XMLDocument: Variant;  
  begin
    XMLDocument := CreateOleObject('Msxml2.DOMDocument.6.0');
    try
      XMLDocument.async := False;
      XMLDocument.load(AFileName);
  //    if (XMLDocument.parseError.errorCode &lt;&gt; 0) then
  //      MsgBox('Install the software. ' +
  //        XMLDocument.parseError.reason, mbError, MB_OK)
  //    else
      begin

    end;
  end;
  
  function NextButtonClick(PageID: Integer): Boolean;
  var
    XMLFile: string;
  begin
    Result := True;
    if (PageId = wpFinished) then
    begin
      XMLFile := ExpandConstant('{pf}\Hell\0\Config.xml');
      if FileExists(XMLFile) then
      begin
        SaveValueToXML(XMLFile, '//@param', PEdit.Text);  //PEdit.text is from a custom input text box in the installer, ignore.
        SaveValueToXML(XMLFile, '//@path',
          ExpandConstant('{reg:HKCU\SOFTWARE\Craps,InstallPath}\Test.exe'));
      end;
    end;
  end;
  </code></pre>
  
  <p>This is my XML file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;stuffs&gt;
          &lt;stuff ident="555" path="C:\Program Files (x86)\Other thing\Other.exe" param="-alive" display="1" priority="0"/&gt;
          &lt;stuff ident="666" path="C:\Program Files (x86)\Craps\test.exe" param="-dead" display="1" priority="0"/&gt;    
  &lt;/stuffs&gt;
  </code></pre>
  
  <p>The problem is that my script always write in the first line. What i need is to always save the nodes in the line that start with <code>&lt;stuff ident="666"</code></p>
  
  <p>Thanks in advance!</p>
