i bow down before your awesomeness :) but, the next step is to be able
to use a user-written resolver in XSLT itself, e.g. for loading DTDs
(other than the stylesheet contianig the resolver code...)

For now though, thanks, Christian, for making the changes!

I’ve already written a catalog resolver in XSLT…

That's good at least...

Io, but i am running the example locally with no http involve, and
using the standalone BaseX jar. But i did have to change it to map
file:


If you add
verbosity = 999
to CatalogManager.properties you will see a log of what it is trying to
resolve which may help (it also logs all the mapping rules it finds).

Yes, they are a bit of a nightmare. Actually i’ve thought about having
the ability to write a URI Resolver in XQuery, 
db:resolve-identifier($system, $public, $purpose, $types) as
xs:anyURI?

but maybe it is too scary!

i’m sorry - i should have included more background and rationale as to
why i did it the way i did, i think.

Perfect.

Perfect.

it is all working for me. Many many thanks!

xmllint and BaseX seem to behave differently on my system. With
xmllint and xsltproc, your examples run fine.

When running the following query…

fetch:xml('all.xml', map { 'dtd': true(), 'catfile': 'saxalog.xml' })

…with or without the xml-resolver-1.2.jar library, I get:

Stopped at .../fetch.xq, 1/10:
[fetch:open] ".../all.xml"Resource "...\nonsense.dtd (Das System kann
die angegebene Datei nicht finden)" not found.

The only difference is that the "Cannot find
CatalogManager.properties" warning appears if the Apache resolver is
in the classpath.

Your example (with the public identifier) returns the expected result
if I replace "nonsense.dtd" with "http://nonsense.dtd;. Do you
experience a similar behavior?

I noticed that the query

  xslt:transform("try2.xsl", "try2.xsl", (), map { 'catalog' : "saxalog.xml" })

runs fine with the snapshot I provided before. And the following query

  declare option db:catfile "saxalog.xml";
  xslt:transform("try2.xsl", "try2.xsl", (), map { 'catalog' : "notfound.xml" })

raises the expected error. Things are different, though, if we replace
"try2.xsl" with doc("try2.xsl"): If the doc function is used, the
document will not be resolved by the XSL transformer, but already by
BaseX.

In a nutshell: You convinced me well enough that we should simplify
things and handle catalogs globally. Understanding catalogs is quite a
challenge in itself, and we shouldn’t necessarily make it even more
challenging. I have simplified the code again, so it looks pretty
similar to your original solution ;)

• If a global catalog file list is defined, it will also be assigned
to the XSL transformer. In fact, that’s the default behavior anyway if
functions like fn:doc are used in BaseX.
• No warnings will be output to standard error, unless
xml.catalog.ignoreMissing is overwritten.

The documentation has been updated, and new snapshots are available.

Hi Andreas,

Yes, that’s true, it got lost in 9.1.2 [1]. Sorry for that.

BaseX 9.2 will be available soon. For now, feel free to use 9.1.1 or
the latest snapshot [2].

Best,
Christian

[basex-talk] Regex j-flag

2019-03-13 Thread Andreas Hartmann
Hi

The "j" flag for regular expressions introduced in version 9.1 doesn't seem
to work in 9.1.2 anymore. For example, matches("Fenster", "\bfenst", "ij")
produces [FORX0001] invalid regular flag 'j'. The same expression works in
9.1.1.

Best Greetings,

Andreas
