Hi Yitzhak
That is an incredibly helpful Xquery example.
Unfortunately I'm unable to get it to run on my Linux machine.
While this (Saxon-HE) works ok:
saxon -s:small.xml -xsl:transform.xsl -o:result.html
basex returns a stacktrace (shown at the bottom of my email) when I run the
basex query below, modelled on yours but using quoting which I think is correct
for linux.
basex -b '$input=small.xml' -b '$stylesheet=transform.xsl' wrapper.xqy
This fails with a
java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length
8
error, although I don't believe I'm using any range/iterator expressions.
I'm using the following files:
transform:xsl:
```xsl
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:akn="http://docs.oasis-open.org/legaldocml/ns/akn/3.0";
exclude-result-prefixes="akn">
<xsl:template match="/akn:akomaNtoso">
<main id="main-content">
<xsl:apply-templates select="akn:judgment"/>
</main>
</xsl:template>
</xsl:stylesheet>
```
small.xml:
```xml
<akomaNtoso xmlns="http://docs.oasis-open.org/legaldocml/ns/akn/3.0";>
<judgment name="judgment">
<meta>
</meta>
<header>
<p>A Header Paragraph</p>
</header>
<judgmentBody>
<paragraph eId="para_1">
<num>1.</num>
<content>
<p>This is the first paragraph of the judgment.</p>
</content>
</paragraph>
</judgmentBody>
</judgment>
</akomaNtoso>
```
wrapper.xqy:
```
declare variable $input as xs:string external;
declare variable $stylesheet as xs:string external;
let $output := substring-before($input, ".") || "_output.xml"
return xslt:transform($input, $stylesheet) -> file:write($output, .)
```
stack trace:
```
$ basex -b '$input=small.xml' -b '$stylesheet=transform.xsl' wrapper.xqy
