[oXygen-user] Problem with Saxon's EXPath/file:exists on Mac

[Stefan Krause]

Hi George,

thanks for your quick response. It provides a useful workaround, but: 

> […] You pass an URI while that expects a file path. […]


From The EXpath-Spec [1]:

»An implementation must accept absolute and relative UNIX/Linux and Windows paths as well as absolute file URIs.«

So I think it is OK to provide an absolute URI for the parameter.


BTW: My attempt to solve the issue in a more general way was file:path-to-native(), but it resolves the URI wrong. file:path-to-native("file:/Users/Stf/Documents/trash/file-exists.xsl") evaluates to »/Applications/oxygenXML 15.2/Users/Stf/Documents/trash/file-exists.xsl« (tested with the stylesheet [2]). Maybe this is the same problem as with file:exists().

Best regards,

Stefan

[2] Modified test stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:xs="http://www.w3.org/2001/XMLSchema"
	xmlns:file="http://expath.org/ns/file"
	version="2.0"
	exclude-result-prefixes="#all">
	<xsl:template match="/">
		<xsl:variable name="file" as="xs:string" select="string(document-uri(/))"/>
		<root>
			<test>
				<xsl:value-of select="$file"/>: <xsl:value-of select="file:exists($file)"/>
			</test>
			<xsl:variable name="file2" as="xs:string" select="substring-after($file, 'file:')"/>
			<test>
				<xsl:value-of select="$file2"/>: <xsl:value-of select="file:exists($file2)"/>
			</test>
			<xsl:variable name="file3" as="xs:string" select="file:path-to-native($file)"/>
			<test>
				<xsl:value-of select="$file3"/>: <xsl:value-of select="file:exists($file3)"/>
			</test>
		</root>
	</xsl:template>
</xsl:stylesheet>

Result:

<root>
	<test>file:/Users/Stf/Documents/trash/file-exists.xsl: false</test>
	<test>/Users/Stf/Documents/trash/file-exists.xsl: true</test>
	<test>/Applications/oxygenXML 15.2/Users/Stf/Documents/trash/file-exists.xsl: false</test>
</root>
