preserveWhiteSpace Property

Specifies the default white space handling.

boolVal = objXMLDOMDocument.preserveWhiteSpace;
objXMLDOMDocument.preserveWhiteSpace = boolVal;

Example

The following script example first loads and displays a file with the preserveWhiteSpace property set to True and then reloads and displays the file with the preserveWhiteSpace property set to False.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
xmlDoc.async = false;
xmlDoc.preserveWhiteSpace = true;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
   var myErr = xmlDoc.parseError;
   WScript.Echo("You have error " + myErr.reason);
} else {
   WScript.Echo(xmlDoc.xml);
   xmlDoc.async = false;
   xmlDoc.preserveWhiteSpace = false;
   xmlDoc.load("books.xml");
   WScript.Echo(xmlDoc.xml);
}


boolVal = objXMLDOMDocument.preserveWhiteSpace;
objXMLDOMDocument.preserveWhiteSpace = boolVal;

HRESULT get_preserveWhiteSpace(
    VARIANT_BOOL *isPreserving);
HRESULT put_preserveWhiteSpace(
    VARIANT_BOOL isPreserving);

Parameters

isPreserving[out, retval][in]

The value that indicates whether default processing preserves white space.

C/C++ Return Values

S_OK

The value returned if successful.

E_INVALIDARG (for get_preserveWhiteSpaceonly)

The value returned if the isPreserving property is Null.

Boolean. The property is read/write. This property is initialized to False.

The preserveWhiteSpace property specifies the default white space handling. When preserveWhiteSpace is True, all white space is preserved, regardless of any xml:space attributes specified in the document type definition (DTD). It is equivalent to having an xml:space="preserve" attribute on every element.

When preserveWhiteSpace is False, the values of any xml:space attributes determine where white space is preserved.

The xml property does not preserve white space exactly as it appears in the original document. Instead, the object model replaces white space present in the original document with a single newline character in the representation returned by the xml property. In a similar way, the text property contains a representation without the leading and trailing spaces and replaces multiple intervening white space characters between words with a single space character.

The text and xml properties preserve white space when the preserveWhiteSpace property is set to True and xml:space on the XML element has the value "preserve."
