RE: creating new lines in textarea input for HTML

hello,

i used to have found this template while surching for a similar problem :

        <xsl:template name="lf2br">
                <!-- import $StringToTransform -->
                <xsl:param name="StringToTransform"/>
                <xsl:choose>
                        <!-- string contains linefeed -->
                        <xsl:when test="contains($StringToTransform,'&#xA;')">
                                <!-- output substring that comes before the 
first linefeed -->
                                <!-- note: use of substring-before() function 
means        -->
                                <!-- $StringToTransform will be treated as a 
string,       -->
                                <!-- even if it is a node-set or result tree 
fragment.     -->
                                <!-- So hopefully $StringToTransform is really 
a string!   -->
                                <xsl:value-of 
select="substring-before($StringToTransform,'&#xA;')"/>
                                <!-- by putting a 'br' element in the result 
tree instead  -->
                                <!-- of the linefeed character, a <br> will be 
output at   -->
                                <!-- that point in the HTML                     
           -->
                                <br/>
                                <!-- repeat for the remainder of the original 
string -->
                                <xsl:call-template name="lf2br">
                                        <xsl:with-param 
name="StringToTransform">
                                                <xsl:value-of 
select="substring-after($StringToTransform,'&#xA;')"/>
                                        </xsl:with-param>
                                </xsl:call-template>
                        </xsl:when>
                        <!-- string does not contain newline, so just output it 
-->
                        <xsl:otherwise>
                                <xsl:value-of select="$StringToTransform"/>
                        </xsl:otherwise>
                </xsl:choose>
        </xsl:template>

Whenever i want to diplay line breaks of a string with a <br/> html element
i just do :

                        <xsl:call-template name="CopyWithLineBreakBR">
                                <xsl:with-param name="string" select="'my 
breaked
                                string'"/>
                        </xsl:call-template>


        <xsl:template name="CopyWithLineBreakBR">
                <xsl:param name="string"/>
                <xsl:variable name="Result">
                        <xsl:call-template name="lf2br">
                                <xsl:with-param name="StringToTransform" 
select="$string"/>
                        </xsl:call-template>
                </xsl:variable>
                <xsl:copy-of select="$Result"/>
        </xsl:template>

hope this help,

matt

Objet : [xsl] creating new lines in textarea input for HTML


The <textarea> input in HTML will take a value that has multiple lines CR/LF
but will not
preserve the line feeds (treated as whitespace).

On the other hand, if I add these using <xsl:text>&#x0a;</xsl:text>, they
show up fine in
the textarea.

So the challenge is, how do I break up the string using XSLT and put in the
above?

I though string-before() would work but realized that it is treating
'&#x0a;' as literal
text.  Is there another way to do this?

Thanks,
Stuart Zakon
