I'm trying to clean up the readability of my code. Using v1. Any help on what I'm doing wrong is greatly appreciated.
XML code that I have:
...
<trusted-servers>mark mike sally</trusted-servers>
...
I want it to display the following way:
mark
mike
sally
Originally, it's displaying in this way using (<xsl:value-of select="trusted-servers"/>):
mark mike sally
What I have tried is:
<xsl:value-of select="string-length(substring-before(trusted-servers, concat(' ', trusted-servers, '<xsl:text disable-output-escaping="yes"><![CDATA[<br />]]></xsl:text>')))" data-type="string"/>
But it throws an error saying that unescaped character < isn't allowed. I tried taking out the <xsl:text disable-output-escaping="yes"><![CDATA[<br />]]></xsl:text> part and replacing it with <br/> but still have the same error. I'm clueless in any other ways of doing it.
Generally speaking, <xsl:text disable-output-escaping="yes">should be avoided as much as possible!
Since you're using XSLT 1.0, the best solution is to write a template which will recursively replace the first space encountered by a <br>, for instance:
<xsl:template match="trusted-servers" name="replace-space-by-br">
<xsl:param name="text" select="."/>
<xsl:choose>
<xsl:when test="contains($text, ' ')">
<xsl:variable name="head" select="substring-before($text, ' ')"/>
<xsl:variable name="tail" select="substring-after($text, ' ')"/>
<xsl:value-of select="$head"/>
<br/>
<xsl:call-template name="replace-space-by-br">
<xsl:with-param name="text" select="$tail"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Assuming xsltproc you have http://exslt.org/str/functions/tokenize/index.html so you can do
<xsl:template match="trusted-servers">
<xsl:for-each select="str:tokenize(., ' ')">
<xsl:if test="position() > 1"><br/></xsl:if>
<xsl:value-of select="."/>
</xsl:for-each>
</xsl:template>
where you declare xmlns:str="http://exslt.org/strings" on the xsl:stylesheet.
