Hi:
A few comments. An .srx file (SAS Report XML) is intended for use in the SAS Enterprise Intelligence/Business Intelligence Platform. An .srx file created in SAS Enterprise Guide is "transformed" to an HTML-ish version of the report by internal transforms in EG.
Then, in other client applications of the BI Platform, such as Web Report Studio, the SAS Add-in for Microsoft Office, and the Information Delivery Portal -- there are also transforms that convert the .SRX report to the form that is appropriate to the client application. When you publish report to a WebDAV repository, in the EI/BI platform, the file is stored as an .srx (SAS Report XML) file.
If you want to know whether there are published XSL transforms to convert SAS Report XML to HTML or other format, I do not believe there are. But if there is ANY information on the specification for SAS Report XML, it will be in the Platform documentation, probably in the Integration Technologies doc. The "official" name might be under SAS Report XML but also might be under SAS Report Object Model.
If you are not using the BI Platform and cannot use the internal transforms, then perhaps you want to take advantage of other destinations, such as HTML, RTF or PDF that can be created with the Output Delivery System.
If you are writing your own ASP application to deliver EI/BI content, then you may want to contact SAS Tech Support for more help. They have some examples of ASP and the Platform here, (but Tech Support may also be able to offer you specific help with your code):
