The use of slashes to represent directory paths in XPath extension functions on Windows operating systems can be interpreted in two ways:

• With double slashes. For example, file://c:/Ftab.txt.

• With single slashes. For example, file:/c:/Ftab.txt.

If you specify double slashes and receive an error message, try specifying single slashes.

For example, the following use of double slashes does not work:

oraext:get-content-from-file-function("file://c:/Ftab.txt","file:
//c:/Ftab_1.xsd","root")

Whereas, the following use of single slashes works correctly:

oraext:get-content-from-file-function("file:/c:/Ftab.txt","file:
/c:/Ftab_1.xsd","root")
