Exist Pragma support

Appreciations on the efforts towards the 1.4 release !

Just as a note I spotted wihin the Option class that the Pattern matcher's grouping of attribute-value pair uses the following regex expression:

"\\s*([\\w\\.-]+)\\s*=\\s*('[^']*'|\"[^\"]*\"|[^\\s]+)"

I think this allows some ambiguity since the last option ("a bunch on non-whitespace characters") could match something starting with a single or double quote. Perhaps you could change [^\s]+ to [^\s>]+.

Also the TimerPragma's "Invalid content" error message is also wrongly taken from that of the Optimize pragma.

I was wondering if anyone could shed some light on writing a pragma, within the XQueryContext, getPragma generates a new Pragma instance, my assumption was that this would access an existing pragma instance within the Context. Can I ask the easiest way of doing this ?

Thanks,

Roger

Hi David,

The Nullpointer check would be a good safe guard anyways since higher up in the eval method, you set InputStream is = null;

I guess I just missed this check. Thnx for your input!

Kind regards

Re: Exist Pragma support

Hi Roger, would you be able to file SF bugs for those two? I ask
because we are so tied up in getting 1.4 out the door, I am afraid
they may get lost otherwise. I imagined the TimerPragma problem could
use fixing before 1.4 and should be allocated a high priority on the
SF bug page, but the regexp may be okay to be fixed after?

Can you explain what you are trying to do a little? Do you need to
keep state between invocations of a pragma?

Re: XSLT transformation is not updated, when included XSLT files changes

I am afraid this is a medium to low priority issue for us.

Can I ask how critical this is to you? And if its really serious, we
may need to upgrade it.

No, you cannot. In these directories the non xml data (aka 'binary documents') are stored.

Why are you worried about these exist-db internal design things?

XQuery Question - Parent Directory


Hello,

Thanks for your help lately.

I am intrigued to find out what location is the parent directory for exist.

Trying to do the following tutorial.

http://en.wikibooks.org/wiki/XQuery/Searching_multiple_collections

They have some files here and I am required to add into the parent
directory.

Thanks in advance,

Re: XSLT transformation is not updated, when included XSLT files changes

It is getting very critical for me.

I have an application that is going live in two weeks time, where the content is created by a number of XSLT files with myriad of included XSLT modules. When a module XSLT file is changed, it is very cumbersome to keep track of which XSLT files to touch to cause reload and see the changes. Sometimes is is easier just to restart eXist to see the update.

In production time this is not an option and having XSLT files automatically reloaded when an included XSLT files changes, is very important for me.

Regards,

Thomas
