Brenton Thomas commented on XERCESC-1773:
-----------------------------------------
The big picture is I want to keep local copies of XMLSchema.xsd and XML.xsd
inside my executable directory. I can not make the assumption with this code
there will be any network access at all allowed from where it will be used and
"the real world" .
So the solution seems to be to use XMLUni::fgXercesSchemaExternalSchemaLocation
to override the suggestion of where to find the base schema's and redirect them
to the local versions.
I have gotten to the point that when the namespaces are being loaded using the
suggestions in the XML doc all is fine - well at least up to the point that
validation fails because I haven't implemented mandatory elements - but that is
is goodness it means validation is working.
but when I try XMLUni::fgXercesSchemaExternalSchemaLocation on blank escaped
strings I end up with
0x000000000012ccc0 "Schema in
d:\Home\Development\StrawberryFields%202.0\StrawberryFields\Common\bin\WIN64\Debug\XML1998.xsd
has a different target namespace from the one specified in the instance
document
(XML1998.xsd is just xml.xsd with a different filename)
but if I escape both the string and the number I get
0x000000000012a130 "An exception occurred! Type:RuntimeException,
Message:Warning: The primary document entity could not be opened.

> Spaces in Filenames problem with XMLUri::normalizeURI

> Key: XERCESC-1773
> URL: https://issues.apache.org/jira/browse/XERCESC-1773
> Project: Xerces-C++
> Issue Type: Bug
> Environment: WindowsXP 64
> Reporter: Brenton Thomas
> Fix For: 2.8.0
>
>
> 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++;
> }
> }
> }
