[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Perl and MSXML3 to transform XML with XSL
 http://www.perl.com/pub/a/2001/04/17/msxml.html This article shows enough details to load an XML document (and an XSL stylesheet) into a DOMDocument: # Load the XML file
$doc_to_transform->{async} = "False";
$doc_to_transform->{validateOnParse} = "True";
$boolean_Load = $doc_to_transform->Load($xml_file);I have figured out how to get detailed error checking out of the two loads. The $doc_to_transform->{parseError} syntax gets me access to line numbers, error reasons and so on. Very nice. if(!$boolean_Load) { # The error message includes file name, line #, position #, and reason. PrintMessage("error at line ".$doc_to_transform->{parseError}->{line}." position ".$doc_to_transform->{parseError}->{linePos}." reason ".$doc_to_transform->{parseError}->{reason}); } The article also shows how to transform them and save the result: # Perform the transformation and save the resulting DOM object to file
$doc_to_transform->transformNodeToObject($style_sheet_doc, $transformed_doc);
$transformed_doc->save("$out_file");Unfortunately the article gives me no hint on how to error check the transformNodeToObject, and I've been unable to figure it out on my own. The closest example I have found is from MSDN: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk30/htm/xmcondetecthandlxslerrors.asp?frame=true They give some JScript examples along this line for transformNode: try
{
result = source.transformNode(style.XMLDocument);
}
catch (exception)
{
result = reportRuntimeError(exception);
}Which calls this function: function reportRuntimeError(exception)
{
return "XSL Runtime Error" + exception.description;
}What is the equivalent of this try/catch in Perl? I assume the syntax is something like: # Perform the transformation and save the resulting DOM object to file
$doc_to_transform->transformNodeToObject($style_sheet_doc, $transformed_doc)
or $transformed_doc->{runtimeError}->{description};This doesn't work; the "or" is always triggered. Any help is appreciated. --James Garriss (MITRE) XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
