[xsl] Late requirement for uniform wrapping of differently generated elements
|
Subject: [xsl] Late requirement for uniform wrapping of differently generated elements From: Wolfgang Laun <wolfgang.laun@xxxxxxxxx> Date: Sat, 11 Feb 2012 16:22:47 +0100 |
My XSLT generates a HTML document containing (almost) nothing except <h*> and <table>. I wrote it as a template reflecting the <html> structure, with called templates pulling in the data from the XML source. It is within these called templates that the various <table> elements (of differing structure) are generated. An new requirement demands that all the various <table> elements are to be wrapped with another <table> (with a single <tr>) for layout purposes, adding one <td> with uniform contents to the <td> containing the original table. I cannot insert two different template calls producing the outer table's introduction and completion, respectively: they each would contain unbalanced data. I know it can be done by adding the new HTML stuff to all the called templates, which isn't nice as it duplicates code, in many different places. If I had realized this new requirement earlier - would there be a good solution while still retaining the "pull" structure? How do I handle the generation of different tables from within a single "wrapper" table template? One big <choose> driven by a parameter seems to be the only option. (Something like a "function reference" for callable templates would enable me to write what I'd consider a "clean" program structure.) I wouldn't be surprised if there is there anything I've overlooked. Regards Wolfgang
