Info

The browser will apply the XSLT stylesheet to the TETML document and then display the resulting text, HTML, or XML output. As an alternative, XSLT processing in the browser can also be initiated from JavaScript code. With Firefox 2 and above you can supply parameters to the XSLT stylesheet with the xslt-param processing instruction:
8.5 XSLT Samples The TET distribution includes several XSLT stylesheets which demonstrate the power of XSLT applied to TETML, and can be used as a starting point for TETML applications. This section provides an overview of the XSLT samples and presents sample output. Section 8.4, »Transforming TETML with XSLT«, page 97 discusses many options for deploying the XSLT stylesheets. More details regarding the functionality and inner workings of the stylesheets can be found in comments in the XSLT code. Some general aspects of the stylesheet samples: > Most XSLT samples support parameters which can used to control various processing details. These parameters can be set within the XSLT code or overridden from the environment (e.g. ant). > Most XSLT samples require TETML input in a certain text mode (e.g. word mode, see »TETML text modes«, page 92, for details). In order to protect themselves from wrong input, they check whether the supplied TETML input conforms to the requirement, and report an error otherwise. > Some XSLT samples recursively process PDF attachments in the document (this is mentioned in the descriptions below). Most samples ignore PDF attachments, though. They are written in a way so that they can easily be expanded to process attachments as well. It is sufficient to select the interesting elements within the Attachments element; the relevant xsl:template elements themselves don’t have to be modified. > All XSLT samples work with XSLT 1. While some samples could be simplified using features from XSLT 2, we wanted to stick to XSLT 1 for better usability. Create a concordance. The concordance.xsl stylesheet expects TETML input in word or wordplus mode. It creates a concordance, i.e. a list of unique words in a document sorted by descending frequency. This may be useful to create a concordance for linguistic analysis, cross-references for translators, consistency checks, etc. List of words in the document along with the number of occurrences: the 207 font 107 of 100 a 92 in 83 and 75 fonts 64 PDF 60 FontReporter 58 ... Font filtering. The fontfilter.xsl stylesheet expects TETML input in glyph or wordplus mode. It lists all words in a document which use a particular font in a size larger than a specified value. This may be useful to detect certain font/size combinations or for quality control. The same concept can be used to create a table of contents based on text portions which use a large font size.
