I wonder why functions like

define-extension
define-xpath-function/lazy
define-xpath-function/eager
define-xpath-function/single-type

are not exported? Does it mean a user should use some other way to
define extensions?

Thank you,
Andrew

Hi

If I define a function like:

(xpath::define-extension func "http://www.somedomain.com/func")
(xpath::define-xpath-function/lazy func test-func (arg1)
  #'(lambda (ctx)
      (funcall arg1 ctx)))

or

(xpath::define-xpath-function/eager func test-func2 (arg1 arg2)
  (concatenate 'string arg1 " " arg2))

Later in xls when I test <xsl:if
test="function-available('func:test-func')"> the test fails.
The function itself works well in xls. Is it expected behavior?

Thank you,
Andrew

Well, if a function works but isn't advertised by function-available,
that sounds like a bug.  Do you have a self-contained test caes?

Thanks
d.

	extension functions?
Message-ID: <AANLkTi=L0M8qVovUKACHGGJSGGhY7cxeYM9K+ry9e388@mail.gmail.com>

If you execute the sample below:

(progn
  (xpath::define-extension func "http://www.test.com/func")
  (xpath::define-xpath-function/eager func test-func (arg1 arg2)
    (concatenate 'string "<content>" arg1 " " arg2 "</content>"))

  (xuriella:apply-stylesheet
   "<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
                 xmlns:func='http://www.test.com/func'
                 version='1.0'>
    <xsl:template match='/'>
       <xsl:value-of select='func:test-func(\"one\", \"two\")' />
    </xsl:template>
  </xsl:stylesheet>"
   "<test-input/>"))

It'll give you
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>
&lt;content&gt;one two&lt;/content&gt;"

What can I do to prevent <content> tag from being escaped?

Thank you,
Andrei

<xsl:value-of select="..." disable-output-escaping = "yes"/>

Thanks! I was trying unescaped-value-of before, but for some reason
the compiler says "undefined instruction".
