Writes a DOM structure as XML data into a file or stream. It can deal both with XML files and XML fragments.
Declarations excerpted from XMLWrite.pas.
procedure WriteXMLFile(doc: TXMLDocument; const AFileName: String); overload; procedure WriteXMLFile(doc: TXMLDocument; var AFile: Text); overload; procedure WriteXMLFile(doc: TXMLDocument; AStream: TStream); overload; procedure WriteXML(Element: TDOMNode; const AFileName: String); overload; procedure WriteXML(Element: TDOMNode; var AFile: Text); overload; procedure WriteXML(Element: TDOMNode; AStream: TStream); overload;
At the moment it supports only the UTF-8 output encoding. The encoding label is not written because it is optional for UTF-8.
The writer provides proper character escaping as required by XML:
- for normal text nodes, the following replacements will be done:
- '<' => '<'
- '>' => '>'
- '&' => '&'
- For attribute values, additionally '"' (#34) gets replaced by '"', and characters #9, #10 and #13 are escaped using numerical references.
- Single apostrophes (') don't need to get converted, as values are already written using "" quotes.
The XML reader (in xmlread.pp) will convert these entity references back to their original characters.
Will raise EConvertError if any DOM node contains an unpaired UTF-16 surrogate in its name or value.
At the moment always uses line endings which are default for the target platform (#13#10 for Windows, #10 for Linux). Moreover, any #13, #10 or #13#10 in input data is treated as a single line-ending.
- The sets of WriteXML() and WriteXMLFile() procedures duplicate each other, one of them is actually redundant.
