save Method
Saves an XML document to the specified location.
Script Syntax
oXMLDOMDocument.save(destination);
Parameters
- destination
- An object. The object can represent a file name, an ASP
Response
object, aDOMDocument
object, or a custom object that supports persistence. See Remarks for more information.
Visual Basic Syntax
oXMLDOMDocument.save(destination)
Parameters
- destination
- An object. The object can represent a file name, an ASP
Response
object, aDOMDocument
object, or a custom object that supports persistence. See Remarks for more information.
Example
The following Microsoft® Visual Basic® example creates a DomDocument
object from a string, then saves the document to a file in the application folder. If you look at the resulting file you will see that, instead of one continuous line of text, after each tag or data string. That is because of the vbNewLine
constant inserted in the string at the appropriate locations.
Private Sub Form_Load() Dim doc As New DOMDocument50 doc.async = False doc.validateOnParse = False doc.resolveExternals = False doc.loadXML _ "<?xml version='1.0'?>" + vbNewLine + _ "<doc title='test'>" + vbNewLine + _ " <page num='1'>" + vbNewLine + _ " <para title='Saved at last'>" + vbNewLine + _ " This XML data is finally saved." + vbNewLine + _ " </para>" + vbNewLine + _ " </page>" + vbNewLine + _ " <page num='2'>" + vbNewLine + _ " <para>" + vbNewLine + _ " This page is intentionally left blank." + vbNewLine + _ " </para>" + vbNewLine + _ " </page>" + vbNewLine + _ "</doc>" + vbNewLine Path = App.Path + "\saved.xml" doc.save Path End Sub
C/C++ Syntax
HRESULT save( VARIANT destination);
Parameters
- destination [in]
- The type of object to save. This object can represent a file name, an ASP
Response
object, an XML document object, or a custom object that supports persistence. See Remarks for more information.
C/C++ Return Values
- S_OK
- The value returned if successful.
- XML_BAD_ENCODING
- The value returned if the document contains a character that does not belong in the specified encoding. The character must use a numeric entity reference. For example, the Japanese Unicode character 20013 does not fit into the encoding Windows-1250 (the Central European alphabet) and therefore must be represented in markup as the numeric entity reference 中 or 中 This version of
save
does not automatically convert characters to the numeric entity references. - E_INVALIDARG
- The value returned if a string was provided, but it is not a valid file name.
- E_ACCESSDENIED
- The value returned if a save operation is not permitted.
- E_OUTOFMEMORY
- The value returned if the save operation must allocate buffers.
- (Other values)
- Any other file system error can be returned in the
save(string)
case.
Example
BOOL DOMDocSaveLocation() { BOOL bResult = FALSE; IXMLDOMDocument *pIXMLDOMDocument = NULL; HRESULT hr; try { _variant_t varString = _T("D:\\sample.xml"); // Initialize pIXMLDOMDocument (create a DOMDocument). // Load document. hr = pIXMLDOMDocument->save(varString); if(SUCCEEDED(hr)) bResult = TRUE; } catch(...) { DisplayErrorToUser(); // Release the IXMLDOMDocument interface. } // Release the IXMLDOMDocument interface when finished with it. return bResult; }
Remarks
The behavior differs based on the object specified by the objTarget
parameter.
Object | Description |
---|---|
string | Specifies the file name. This must be a file name rather than a URL. The file is created, if necessary, and the contents are replaced entirely with the contents of the saved document. This mode is not intended for use from a secure client, such as Microsoft® Internet Explorer.
dim xmldoc set xmldoc = Server.CreateObject("Msxml2.DOMDocument.5.0") xmldoc.load("c:\myfile.xml") xmldoc.save(Server.MapPath("sample.xml")) The ASP dim xmldoc set xmldoc = Server.CreateObject("Msxml2.DOMDocument.5.0") xmldoc.load(Server.MapPath("sample.xml")) xmldoc.save(Response) |
IXMLDocument Object |
Duplicates the original document. It is the equivalent of saving the document and reparsing it. The document goes through full persistence through XML markup, thereby testing the persistability of your XML document.
<script language="jscript"> var xmldoc1 = new ActiveXObject("Msxml2.DOMDocument.5.0"); var xmldoc2 = new ActiveXObject("Msxml2.DOMDocument.5.0"); xmldoc1.load("sample.xml"); xmldoc1.save(xmldoc2.XMLDocument); </script> |
Custom object supporting persistence | Any other custom COM object that supports QueryInterface for IStream , IPersistStream , or IPersistStreamInit can also be provided here, and the document will be saved accordingly. In the IStream case, the IStream Write method will be called as it saves the document; in the IPersistStream case, IPersistStream Load will be called with an IStream that supports the Read , Seek , and Stat methods. |
External entity references in <DOCTYPE>
, <ENTITY>
, <NOTATION>
, and XML namespace declarations are not changed; they point to the original document. A saved XML document might not load if the URLs are not accessible from the location in which you saved the document.
Character encoding is based on the encoding attribute in the XML declaration, such as <?xml version="1.0" encoding="windows-1252"?>
. When no encoding attribute is specified, the default setting is UTF-8.
Validation is not performed during save
, which can result in an invalid document that does not load again because of a specified document type definition (DTD).
