[xquery-talk] External Variable on AltovaXML 2007

[Gerald Sheehan]

Hi Timothy,

To solve the problem I'd use a tokenize on a external parameters list
XQuery:

<result>
{
for $a in tokenize($try, "\s+")
return
<erg>{document($a)/root/chil/text()}</erg>
}
</result>
	


Calling Code should use AddExternalVariable("try", "file1.xml file2.xml
file3.xml")



Best regards,

Jerry

Subject: [xquery-talk] External Variable on AltovaXML 2007

Hello,
I want to pass an XML-String to the AltovaXML 2007 XQuery engine as
external variable. Inside of the xquery, i want to iterate over the
given variable with the for-expression. But, how do i convert the
external XML-String into a xml-document for processing? In saxon or
xalan it is possible to pass the external variables as InputSources, but
how should this be done in AltovaXML? Is there anyone, who had made some
experiences with AltovaXML? It seems to be quiet easy.

My Code looks like this:

IXQuery q = AltovaXMLFactory.getInstance().getXQueryInstance();
q.addExternalVariable("try", "<root><chil>Ich</chil></root>");
q.setOutputEncoding("UTF-8"); q.setXQueryFileName("d:\\test.xq");
String resultString = q.executeAndGetResultAsString(); if (resultString
== null ) { System.out.println("XQuery error : "
+ q.getLastErrorMessage());
}
else{
System.out.println("Transform contents>>" + resultString ); }

My XQuery like this:
declare variable $try external;
<result>
{
for $a in $try
return
<erg>{$a/root/chil/text()}</erg>
}
</result>

Thx in advance.
Timothy
