> 3.1 maps and arrays I found a simple test case causing a
> java.lang.NullPointerException.
> Sample XSLT:

>
> {code:java}
> <?xml version="1.0" encoding="utf-8"?>
> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
> version="3.0"

> xmlns:array="http://www.w3.org/2005/xpath-functions/array";
> exclude-result-prefixes="xs map array">
> <xsl:output method="xml" indent="yes"/>
> <xsl:template match="json">
> <tags>
> <xsl:variable name="xdm-map" select="parse-json(.)"/>
> <xsl:for-each select="map:get($xdm-map, 'data')">
> <value>
> <xsl:value-of select="."/>
> </value>
> </xsl:for-each>
> </tags>
> <xsl:comment>Run with <xsl:value-of

> Sample XML:
> {code:java}
> <root>
> <json>{ "name" : "foo", "data" : [3,2,1] }</json>
> </root>{code}
> Output:
> {noformat}
> <?xml version="1.0" encoding="UTF-8"?>

> Zeilennummer14; Spaltennummer56; java.lang.NullPointerException{noformat}
> Expected output is e.g.
> {code:java}
> <?xml version="1.0" encoding="UTF-8"?>
