[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: Why are there no XSLT processors implemented in XS
 Thanks Tony, that is really nice!
Same output (at bottom, besides XML-declaration).
Did run this on a 2.2GHz i7 processor, while naxos.xsl was running java
process had between 160% and 224% CPU utilization, which is reflected in
real vs user time.
As next step I wanted to see, whether naxos.xsl can run naxos.xsl ... :-)
But I got stopped at this very littly sample, further efforts seem
worthless:
$ cat ab.xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xml" href="double.xsl"?>
<a>1<b>2</b>3</a>
$
$ cat double.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:template match="/">
<out>
<xsl:copy-of select="."/>
<xsl:copy-of select="."/>
</out>
</xsl:template>
</xsl:stylesheet>
$
$ java com.icl.saxon.StyleSheet -a ab.xml ; echo
<?xml version="1.0" encoding="utf-8"?><out><?xml-stylesheet type="text/xml"
href="double.xsl"?><a>1<b>2</b>3</a><?xml-stylesheet type="text/xml"
href="double.xsl"?><a>1<b>2</b>3</a></out>
$
$ java com.icl.saxon.StyleSheet ab.xml ../naxos.xsl ; echo
<out></out>
$
naxos sample execution:
$ time java com.icl.saxon.StyleSheet user.xml ../naxos.xsl

To "[s]ee examples of what XSLT should never have been made to do." [1],

Naxos is very slow and memory-hungry. Stylesheets larger than
toy-sized will probably fail to run even if you specify a large
heap for the JVM with -Xmx.
