Subject: Re: [xsl] Plain Text Handling in XSLT Output From: "andrew welch" <andrew.j.welch@xxxxxxxxx> Date: Wed, 7 Jun 2006 11:11:48 +0100 |
Hello,
i bother with the handling of plain text in xslt. My problem is that i have to insert plain text combined with values to the output depending on if a node exists or not (which is a very common task i guess). So there are many xsl:if test=exists(...) statements inside my xslt.
1. Prob: White spaces If i have a xslt like this: ... <xsl:value-of select="Firstname"/> <xsl:value-of select="Lastname"/> ... I always get this output: ... FirstnameLastname ... How do i insert a white space between (these) two values?
Whitespace only text nodes get dropped by default - that means any text node consisting soley of whitespace (like the whitespace used to indent your XSLT).
So with that in mind, use <xsl:text> </xsl:text> or <xsl:value-of select="concat(Firstname, ' ', Lastname)"/>
2. Prob: Line Feed & Carriage Return The xslt: ... <person> <xsl:if test="exists(mds:node17)"> <name> <xsl:value-of select="node17"/> <xsl:if test="exists(node18)"> (<xsl:value-of select="node18"/>) </xsl:if> </name> </xsl:if> </person> ... This is the expected output: ... Lastname (Function) ... But this is the real output: ... Lastname (Function) ... How can i control if a linefeed is added or not? Is there a possibilty to remove or add a linefeed with xslt to the output?
Here the text node contains a '(' so it doesn't get dropped, and the text node consists of the carriage return and indetation that you've used to indent your code - which is what your are seeing in your output. To avoid this write all the code inline, or use concat.
Also, rather than use xsl:test="exists(...)" just use apply-templates, as then if the element exists it will be processed, otherwise it wont:
<person> <xsl:apply-templates/> </person>
<xsl:template match="mds:node17"> <name> <xsl:value-of select="."/> <xsl:apply-templates/> </name> </xsl:template>
<xsl:template match="mds:node18"> <xsl:value-of select="concat('(', node18, ')'"/> <xsl:template>
