RE: [xsl] applying templates out of a for-each
Subject: RE: [xsl] applying templates out of a for-each From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Fri, 29 May 2009 19:59:07 +0100 |
xsl:for-each changes the context. If you want to use the original context within the for-each, you need to first bind it to a variable, for example: <xsl:variable name="this" select="."/> <xsl:for-each select="...."> <xsl:apply-templates select="$this/(//*[name()=...])"/> Regards, Michael Kay http://www.saxonica.com/ http://twitter.com/michaelhkay > -----Original Message----- > From: Detlef Heyn [mailto:detlef.heyn@xxxxxxxxx] > Sent: 29 May 2009 19:29 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] applying templates out of a for-each > > Hi my dear experts > > > I would appreciate your help with a problem i have. > > From a xml file i read the content of an element wich i > interpret in many possible ways for it's a config file for my > stylesheet. > > This info i give to a template as a parameter simply called "input". > > One way i interpret the value is as an element name wich > content i want to select. > > This works fine until i use the following code: > > ================================================== > <config-input>show_element:Elementname</config-input> > ========================= > <xsl:template name="select"> > <xsl:param name="input"/> > <xsl:choose> > ... > <!-- show element --> > <xsl:when test="contains($input,'show_element:')"> > > <xsl:apply-templates select="//node()[name() = > substring-after($input,':')]" mode="pure"/> > > </xsl:when> > ... > </xsl:choose> > </xsl:template> > ========================= > > but if i want to apply more than one element-content with the > help of a for-each over the readed config-input (wich im > tokenizing to seperate the certain element names) i get this error: > > "F[Saxon-B 9.0.0.6]Cannot select a node here: the context > item is an atomic value > URL: http://www.w3.org/TR/xpath20/#ERRXPTY0020" > > ================================================== > <config-input>show_element:Elementname1 > Elementname2</config-input> ========================= > <xsl:template name="select"> > <xsl:param name="input"/> > <xsl:choose> > ... > <!-- show element --> > <xsl:when test="contains($input,'show_element:')"> > <xsl:for-each select="tokenize(substring-after($input,':'),' ')"> > <xsl:variable name="temp_name" select="string(.)"/> > <xsl:apply-templates select="//node()[name() = $temp_name]" > mode="pure"/> > </xsl:for-each> > </xsl:when> > ... > </xsl:choose> > </xsl:template> > ========================= > > I understand that Saxon has a problem with applying templates > inside of a for-each-loop wich is all about selecting atomic > values (strings in this case) > > > * Do I guess right or don't i catch the real cause? > > * And how, if possible, do i get it work as intented? > (I'm afraid I've just overseen a simple thing) > > > > Thanks a lot for your help in advance. > > have a good time > > D.
