Matt AdamsSubject: How to validate if file or directory exists?
Author: Matt Adams
Date: 14 Oct 2004 04:00 PM
Assume there is an element like

<file attr="D:\test\proj12\log.txt" .... />

How do I validate resp. find out from inside a XSLT stylesheet
if the file mentioned in the attribute really exists?

Is there a function like

<value-of select="fileexists(//file[@attr])" />

Keep in mind. If I would write

<value-of select="exists(//file[@attr])" />

I would test if the attribute exists. That is not what I want.
I want to test the outside (from the XML doc) world existence of
a file defined by the attr value.

Hi Matt,

XSLT doesn't offer a direct solution , so I am presenting 3 way
taking advantage of the different extension function architectures.

-------------------------------------------------------
Microsoft MSXML 3/4 and .NET

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:user="http://www.stylusstudio.com/file-utilities">

<msxsl:script language="JScript" implements-prefix="user">
<![CDATA[
fso = new ActiveXObject("Scripting.FileSystemObject");
function fileExists(filename){
return fso.FileExists(filename);
}

// With .NET XSLT processor we need to use the Framework API
//function fileExists(filename){
// return System.IO.File.Exists(filename);
//}

]]>
</msxsl:script>

<xsl:template match="/">
<xsl:value-of select="user:fileExists('c:\AUTOEXEC.BAT')"/>
<xsl:value-of select="user:fileExists('c:\AUTOEXEC.BAT_')"/>
</xsl:template>
</xsl:stylesheet>

-------------------------------------------------------
Apache Xalan

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan"
extension-element-prefixes="user"
xmlns:user="http://www.stylusstudio.com/file-utilities">

<xalan:component prefix="user" functions="fileExists">
<xalan:script lang="javascript">

// The JavaScript engine let us access the standard Java API

function fileExists(filename){
f = new java.io.File(filename);
return f.exists();
}
</xalan:script>
</xalan:component>

<xsl:template match="/">
<xsl:value-of select="user:fileExists('c:\AUTOEXEC.BAT')"/>
<xsl:value-of select="user:fileExists('c:\AUTOEXEC.BAT_')"/>
</xsl:template>
</xsl:stylesheet>



-------------------------------------------------------
Apache Xalan; Saxon 6.x/ 8.x using a java extension function

FileExists.java

public class FileExists{
public static Object fileExists(String FileName) {
return new Boolean(new java.io.File(FileName).exists());
}
}

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:util="FileExists">
<xsl:template match="/">
<xsl:value-of select="util:fileExists('c:\AUTOEXEC.BAT')"/>
<xsl:value-of select="util:fileExists('c:\AUTOEXEC.BAT_')"/>
</xsl:template>
</xsl:stylesheet>


Hope this helps

Ivan
