Character References get broken

[akond]

(let [stylesheet          (xsl/stylesheet {:version 3.0}
                              (xsl/variable {:name "break1" :select "'
'"})
                              (xsl/variable {:name "break2"}
                                (xsl/text "\n"))
                              (xsl/template {:match "a"}
                                [:b]
                                [:p (xsl/value-of {:select "$break1"})]
                                [:p (xsl/value-of {:select "$break2"})]))
        compiled-stylesheet (xslt/compile-sexp stylesheet)]
    (xslt/transform compiled-stylesheet "<a/>"))

gives me

<b/>\n<p>&amp;#x0A;</p>\n<p>\n</p>

which is weird. I'd expect to see '
' not an amp.

Have you checked whether Sigel behaves differently than Saxon (e.g. by running the equivalent XSL transformation using the Saxon CLI)?

[eerohele]

I haven't used XSLT in years, so my memory on this topic is vague, but if I recall correctly, you can control how entity references appear in the output using the xsl:output element.

[akond]

input.xml

<?xml version="1.0" encoding="UTF-8"?>
<a/>

transform.xsl

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0">
  <xsl:variable name="break1" select="'&#x0A;'" />
  <xsl:variable name="break2">
  <xsl:text>
</xsl:text>
  </xsl:variable>


  <xsl:template match="a">
    <b/>
    <p>
     <xsl:value-of select="$break1"/>
   </p>
  <p>
     <xsl:value-of select="$break2"/>
   </p>
  </xsl:template>
</xsl:stylesheet>

java -cp Saxon-HE-9.9.1-5.jar net.sf.saxon.Transform -s:input.xml -xsl:transform.xsl -o:output.xml

gives me

<?xml version="1.0" encoding="UTF-8"?><b/><p>
</p><p>
</p>

which means saxon recognizes '
' all right.

[eerohele]

Oh, I see now that I read the original issue description too hastily; apologies. I'll take a look when I get the chance.

[eerohele]

Sorry for the delay! Life gets in the way.

This seems to be an issue in clojure.data.xml:

λ clj -Srepro -Sdeps '{:deps {org.clojure/data.xml {:mvn/version "0.2.0-alpha9"}}}'
Clojure 1.12.3
user=> (require '[clojure.data.xml :as xml])
nil
user=> (xml/emit-str {:tag :a :attrs {} :content ["
"]})
"<?xml version=\"1.0\" encoding=\"UTF-8\"?><a>&amp;#x0A;</a>"
user=>

This seems like a bug to me, but I'm not familiar enough with clojure.data.xml to say for sure. In any case, it's not something I can fix in Sigel. If you discover a way to coax clojure.data.xml to emit entity references properly, I can look into configuring Sigel to use that way.
