Understanding How ePublisher Works : Understanding the Transformation Process : Processing Files by Type
 
Processing Files by Type
Once source documents are transformed into WIF, XSL processing can begin. The next question is about how to organize the XSL processing. ePublisher gives you the flexibility you need to define a workflow without the drudgery. While some processes and standards require intimate knowledge of an XSL transform’s input and output file names, ePublisher uses knowledge of an XSL transform’s input and output file types. This distinction is subtle but powerful.
Consider processing XSL with exact file names:
*xslt doctoc.xsl alpha.xml > alpha_toc.xml
*xslt doctoc.xsl delta.xml > delta_toc.xml
*xslt grouptoc.xsl alpha_toc.xml delta_toc.xml > group_toc.xml
Now consider using file types in place of file names:
*xslt doctoc.xsl Source > Doc_TOC
*xslt grouptoc.xsl Doc_TOC > Group_TOC
Using file types in place of file names simplifies the specification, where the file types are defined as follows:
 
File Type
File Names
Source
alpha.xml
delta.xml
Doc_TOC
alpha_toc.xml
delta_toc.xml
Group_TOC
group_toc.xml
With the file type approach, you need to specify xslt doctoc.xsl Source > Doc_TOC only once. This specification runs for every Source type document found and generates the corresponding Doc_TOC output files.
