Subject: RE: [tag] Re: Example of a potentially executable (XPath 2) Test Assertion for OASIS UBL XML Invoice
Stephen: It is probably better to separate the doc(...) function call from the rest of the Xpath. When all this is compiled into an XSLT script, we can put it back together using variables. So if not the Xpath processor, at least the XSLT processor will be able to handle this. See the following sample that I used time ago: <xsl:template match="/equiprogram/reportpair" priority="1"> ... <xsl:variable name="repfileB" select="( here, an Xpath that returns the URL of a document. The URL comes from an element inside the matched "/equiprogram/reportpair" element (from input to this XSLT).)"/> ... <xsl:variable name="reportBdoc" select="document($repfileB)"/> <!-- access dynamically the report file B document --> ... <xsl:for-each select="$reportBdoc/wsi-report:report/wsi-report:artifact/wsi-report:entry[@referenceID=$entryAid]/wsi-report:assertionResult[@id=$arAid]"> ... <!-- iterate on some elements inside the report file B document --> ... </xsl:for-each> Jacques -----Original Message----- From: stephengreenubl@gmail.com [mailto:stephengreenubl@gmail.com] On Behalf Of Stephen Green Sent: Thursday, June 25, 2009 3:16 PM To: TAG TC Subject: [tag] Re: Example of a potentially executable (XPath 2) Test Assertion for OASIS UBL XML Invoice One more thing I'd especially note though is that I'm aware I'm being a bit too ambitious using the XPath 'doc()' function - trying to use it with a URL for an online document. Even when I remember to enclose the URL in quotes, it seems a typical XPath processor isn't obliged to actually go off and get the document from the Internet. I realise this is a bit out of scope though in that it is really related to an XPath binding rather than TAs per se. It will probably be a matter of facilitating the collating of metadata and other data the test suite will rely on if the TA is going to be executable as a TA. A proof of concept, if you will, for the executability use case - not part of TA modelling or markup design perhaps.
