Turning off inappropriate errors?
Hello, I have an XSL-FO file that I want to generate into PDF. Along with the usual FO content, the file contains miscellaneous attributes that are not part of the XSL namespace. My goal is to embed a variety of custom tags into the FO I'm generating that will later be used by an in-house automated testing tool. According to the XSL-FO spec, I should be able to do this. Specifically, section 2.2 of the spec states the following: An element from the XSL namespace may have any attribute not from the XSL namespace, provided that the expanded-name of the attribute has a non-null namespace URI. The presence of such attributes must not change the behavior of XSL elements and functions defined in this document. Thus, an XSL processor is always free to ignore such attributes, and must ignore such attributes without giving an error if it does not recognize the namespace URI. Such attributes can provide, for example, unique identifiers, optimization hints, or documentation. Despite this statement in the XSL-FO spec, I find that FOP gives me a bunch of error messages like this: [ERROR] property 'xform:resourcePath' ignored Obviously, FOP is correctly ignoring the stuff it does not recognize. However, this does not comply with the spec which says that this condition should not give an error. Is there any way to configure FOP so that it will not flag these attributes from an unrecognized namespace as errors? I don't want to turn off the flagging of real errors, just these particular ones that probably shouldn't be there. Any ideas?

The sample program reads an external XML file generated from an Access DataBase. Transformation 1 generates a DOMResult which contains up to about 400 records from the DB. They only add about 1k each to the memory requirements. Transformation 2 reads a new DOMSource( theDOMResult.getNode() ); and generates a SAXResult() that uses the FOP Driver to write a PDF file. This demonstrates enough performance improvements to cut down his execution time significantly. I also pointed out that LOGGING is a performance hog.

That way, one might be able to gather aggregate data, but not have as much of a performance penalty.

RE: FOP being very slow.
Yes, logging appears to be overdone within FOP, even if a NULL logger object is chosen, a lot of function calls are still being made. I haven't researched Xalan much yet, but their system may be a good guide on the amount of logging appropriate for our system.

Re: RE : renderer postscript : border painting
Salut Philippe I haven't had time, yet, to run the debugger, but I think it's pretty obvious now what going wrong. If you look that PostScript file you sent me in a text editor you can see that there is a line 1.0 1.0 1.0 setrgbcolor at the beginning of page 1 which is missing on page 2. You can patch src/org/apache/fop/render/ps/PSRenderer.java. Find the method useColor(float, float, float) and remove the line with the if. This will disable a dumb and obviously buggy optimization attempt. It will certainly increase the size of the PostScript file for the moment but should get rid of the bug. Rebuild FOP after modifying. If I find some time I'll see if I can find a better solution. I probably have the same problem in the dev version.

John Austin wrote: and similar treatment for the StreamSources used to read in the XML and XSLT files. That's usually uncritical, because XML parsers tend to buffer themself. IIRC recent Xerces uses an 8k buffer by default (which means you get long stretches of XML text as a series of characters() events, each dumping 8k text on you).

Oops, debug dumps are controlled by a static variable in the hyphenator, and are by default disabled. You can enable it by doing the following: 1. Get a JDK and the FOP source distro. 2. Open the file src/org/apache/fop/layout/hyphenation/Hyphenator.java in a text editor 3. Change the initialization of the errorDump variable to true. 4. Recompile by running build.bat. I still believe the cause of the problem is malformed XML, perhaps an encoding problem. Use another XML tool (not XML Spy) to verify your XML is free of this problems.
