Description

When using a filename containing spaces that has been escaped by a %20 you end up with problems if the space is followed by a number. For example if you have a directory "D:\Home\Development\StrawberryFields 2.0" you need to escape it to give "D:\Home\Development\StrawberryFields%202.0" - which is obviously going to break because it confuses the 2 at the end. To fix this you escape the number following the space to give "D:\Home\Development\StrawberryFields%20%32.0" .

This is OK in terms of providing a legal schemaLocation except....

The routine XMLUri::normalizeURI then takes the escaped name and unescapes it to return a form the system recognises. What it needs to do is parse through the string and unescape everything - not just the %20

void XMLUri::normalizeURI(const XMLCh* const systemURI,
XMLBuffer& normalizedURI)
{
const XMLCh* pszSrc = systemURI;

normalizedURI.reset();

while (*pszSrc) {

if ((*(pszSrc) == chPercent)
&& (*(pszSrc+1) == chDigit_2)
&& (*(pszSrc+2) == chDigit_0))

{ pszSrc += 3; normalizedURI.append(chSpace); }

else

{ normalizedURI.append(*pszSrc); pszSrc++; }

}
}
