Not all xsl output is captured for use in PHP
0%
Description
We use xsl to validate supplied xml. It outputs useful debugging info when a xml file processed with it fails.
When the attached saxonex.php is run from the cli, the following info is printed to stdout, but it doesn't seem to be able to be captured for use within PHP. I can verify it is not output generated or seen by PHP by wrapping the processor in an ob_start(), ob_end_clean() - the xsl output I require is still displayed, excluding the final line produced by php.
Attached are the files and script I am testing with. The example xml file should fail and produce the following output indicating that the last tag is empty:
# php saxonex.php

Hi thanks for reporting the problem you have found. The capture of xsl:message is missing from Saxon/C. There needs to be a message listener interface similar to what is available in Saxon Java and .Net products.
I will add this feature in the next release of Saxon/C.

Update:
I have added the feature to capture the xsl:message outputs as an XdmValue. The method getXslMessages() returns the XdmValue which is the sequence of XdmNode objects. I have decided to use the property 'm' to switch on this feature, which is consistent with the Java command-line options.
TODO: Add interface to the PHP extension.
This will be available in the next release.

My attempt at adding this mechanism is not quite right. The problem is the xsl:messages will only be available at the end of the transformation. There needs to be a way of making them available immediately as to when it is reached in the transformation therefore informing the user as to where it has happened.
There needs to be some event listener on the C/C++ side. Currently investigating how to do this.
