PDFlib TET で、TETML を HTML に変換するサンプルプログラムです。
<?xml version="1.0"?>
<!--
(C) PDFlib GmbH 2008 www.pdflib.com
Purpose: convert TETML to HTML
Required input: TETML in wordplus mode
Stylesheet parameters:
debug: 0: no debug info, >0: increasingly verbose
toc-generate: 0: no table of contents, 1: generate table of contents
toc-exclude-min, toc-exclude-max:
Specify a range of pages to exclude from the generation of the HTML
table of contents. This can be used to prevent duplicate entries if
also entries in the PDF table of contents are detected as headings
because of their font size.
h<n>.min-size, h<n>.max-size, with n=1..5:
"Para" elements must include at least one character whose size is greater
or equal to the h<n>.min-size parameter and less than or equal to the
h<n>.max-size parameter to be recognized as a h1..h5 heading
