Subject: [xsl] Efficiency, use param in key? From: Christopher_Dant@xxxxxxxxxxxxxx Date: Fri, 2 Aug 2002 18:36:44 -0700 |
On working a stylesheet that processes a multimedia-course storyboard and returns text, CRLF-delimited, sorted, lowercase, no-duplicates filenames I have several questions: 1. is there anything I should do to improve it (make it more efficient)? 2. is it possible to use the param "ele" in key, apply-templates and template? This would make it possible for a single stylesheet to look for file_audio, file_video or file_graphic tags. 3. Or perhaps I should actually ask, is there a way to rework my approach so I can parameterize it? Stylesheet: <xsl:output method="text" encoding="ISO-8859-1" indent="no"/> <xsl:param name="ele">file_audio</xsl:param> <xsl:variable name="lc" select="'abcdefghijklmnopqrstuvwxyz'"/> <xsl:variable name="uc" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/> <xsl:key name="fn" match="file_audio" use="@fileref"/> <xsl:template match="/"> <xsl:apply-templates select="//file_audio"> <xsl:sort select="@fileref"/> </xsl:apply-templates> </xsl:template> <xsl:template match="file_audio[generate-id() = generate-id(key('fn', @fileref)[1])]"> <xsl:value-of select="translate(@fileref, $uc, $lc)"/> <xsl:text disable-output-escaping="yes">
</xsl:text> </xsl:template> Excerpts of sample input: <frame id="01" type="a" parms="a"> <txt_scr lang="ENG"/> <txt_aud>Click on a button in front of the module you wish to begin and...</txt_aud> <file_audio fileref="coursemenu.mp3"/> </frame> . . . <frame id="01"> <txt_scr lang="ENG">Welcome to the Intercom Plus training!</txt_scr> <txt_avi>{Zelda} Hi, welcome to the Intercom Plus Training! I am Zelda Morales...</txt_avi> <file_avi start_frame="1" end_frame="359" fileref="__A_.0010.001.avi" /> </frame> . . .
