Description

Under some circumstances, a Windows styled absolute path for the command line option -catalog causes an error "Malformed URL"

The specific circumstances in my case are:

stylesheet A imports a stylesheet B, and the path to the imported stylesheet is given as an URN
catalog A references catalog B, catalog B resolves the path to stylesheet B
catalog B and stylesheet B reside within a subdirectory relative to stylesheet A and catalog A

The execution fails only, if the path to the catalog is given as an absolute path in Windows style. If the same catalog is refered as a relative path or an URI, the transformation succeeds.

The example files are attached to this ticket, the command line was

C:\_trash\saxonica>Saxon-PE\bin\Transform.exe -xsl:importing-stylesheet.xsl -it:main -catalog:c:\_trash\saxonica\catalog.xml

Im using Saxon Saxon-PE 9.7.0.7N on Windows 10 Build 1607

Hi,

My apologies in taking so long to look at this bug issue. I did not see the problem on my Windows 7 machine, but when I tried running the same example on a different machine running with Windows 10 I reproduced the same exception you reported. Investigating the bug.

Is there any chance that you will fix it in the near future? Otherwise, I have to write a workaround on my side now. Thank you.

This problem of the "Malformed URL" also happens on the Java platform in Windows 10. We can narrow down this issue to the Java platform as Saxon .NET is cross compiled from the Java product.

Update:

Still investigating this one, which led me to look at the source of the xml-resolver-1.2.jar. This library is doing the mapping of catalog files to the URN.

For some reason the variable vector 'catalogEntries' which is held in the class Catalog.java of the xml-resolver.jar is empty under Windows 10 when we are doing the resolving. A call is made to resolveLocalURI within which failure to locate the urn in the catalogEntries vector. This results in a fallback, which is to use the supplied uri string which is a urn in our case. A Malformed URL Exception is subsequently thrown.

We are setting the system property xml.catalog.files to the value supplied in the -catalog option.

It's not well documented, but it seems this system property expects to find a URI rather than a filename.

So the following work around should work:

-catalog:file:///c:/_trash/saxonica/catalog.xml

For the future, if the -u option is set or if the supplied value begins with http:// or file:// option then we should use it unchanged otherwise we should assume we have been given a file name and convert it to URI.

Do you have any idea when v9.8 will be released? Can you merge the bugfix back to the 9.7 branch? Thank you.

Hi,

We will look if this can be retrofitted to the 9.7 branch.

9.8 is now in the testing phase. Hopefully it's now weeks rather than months away. But we let it cook until it tastes right, rather than deciding on a date in advance.
