substringData Method
Retrieves a substring of the full string from the specified range.
JScript Syntax
strValue = oXMLDOMCharacterData.substringData(offset, count);
Parameters
offset
A long integer value indicating the offset, in characters, from the beginning of the string. An offset of zero indicates copying from the start of the data.
count
A long integer value indicating the number of characters to retrieve from the specified offset.
Return Value
A string. Returns the substring.
Example
The following script example creates an IXMLDOMComment
object (comment), and then uses the substringData
method to retrieve the first five characters of the object.
Note
You can use books.xml to run this sample code.
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.6.0");
var comment;
var MyStr;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
var myErr = xmlDoc.parseError;
WScript.Echo("You have error " + myErr.reason);
} else {
comment = xmlDoc.createComment("Hello World!");
MyStr = comment.substringData(0, 5);
WScript.Echo(MyStr);
}
Output
Hello
C/C++ Syntax
