Re: [xsl] Measure the length of an XML document in bytes

[Mukul Gandhi <gandhi.mukul@xxxxxxxxx>]

You can configure Xalan-J in XMLSpy 2005 EE as follows:

In Tools | Options | XSL

Specify in "External Transformation Program"
java org.apache.xalan.xslt.Process -in %1 -xsl %3 -out %2 -param
filename node.xml

Xalan-J's JAR file should be in JVM's CLASSPATH.

(The namespace of Java class need not be changed)

Mukul
