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

["Khorasani, Houman" <houman_khorasani@xxxxxxxxxxxxxx>]

Cheers!  Finally it's working.  How could I overlook the package folder?
:)

Thank you guys so much for your help.


I have just one last question to this topic:

<xsl:stylesheet version="1.0"
xmlns:my-class="xalan://ELSPackage.XMLGetFileSize"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";

Having the my-class namespace in the style sheet; it appends the
namespace to every created XML tag.

e.g.:

<xsl:element name="OrderRequest">

Becomes in the output:
<OrderRequest xmlns:my-class="xalan://ELSPackage.XMLGetFileSize">

How do I prevent that each XML tag retrieves this namespace?

I tried to solve it in this way, but it doesn't work:

<xsl:stylesheet version="1.0"
xmlns:my-class="xalan://ELSPackage.XMLGetFileSize"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
exclude-result-prefixes="OrderRequest">


Any idea?
Thanks
Houman

Hi,

I think you should place the folder that contains the class in the
classpath, not the class itself. Try replacing C:\Header\Utility.class
with C:\Header\.

 >>>package MyPackage;

Also the code suggests that the Utility class is inside a package, so
you will need to create a MyPackage folder in C:\Header and place the
class there.


Regards,
George
