Subject: Re: [xsl] Insert character for missing nodes From: Michael Ludwig <mlu@xxxxxxxxxxxxx> Date: Thu, 30 Oct 2008 16:52:19 +0100 |
<business> <name>Hot Dog Stand</name> <address>123 Main St</address> <url>http://www.hotdogstand.com</url> </business> <business> <name>Joe's Pizza</name> <address>213 Pine St</address> </business>
Because Joe's Pizza is missing the url node, I don't get a pipe, which throws off my columns. Is there a way to test for all possible nodes, and where any are missing, to insert a character?
Very often in XSLT, your process is mainly data-driven. The program reacts to input.
In your example, however, you want to guarantee a certain structure that may be missing in your input. A simple way to guarantee this structure is to code it in your program:
<xsl:template match="business"> <xsl:copy> <name><xsl:value-of select="name"/></name> <address><xsl:value-of select="address"/></address> <url><xsl:value-of select="url"/></url> </xsl:copy> </xsl:template>
You may also simply leave out the element constructors (like <name>...</name>) and separate your <xsl:value> elements by <xsl:text>|</xsl:text> to guarantee the pipe-structure. This works for 1.0, too.
