How to format Sharepoint lookup column XSL values - xslt

Question

I have a Sharepoint list, and one of the columns is a lookup column that returns multiple values, separated by a semi-colon. I would like to display these items as separate lines in the output, instead of as a single line with the separator. The xsl for the field in question is as follows:
<xsl:template match="FieldRef[(#Encoded) and #Name='Project_x0020_Tasks']" ddwrt:dvt_mode="body" mode="Lookup_body" ddwrt:ghost="show">
<xsl:param name="thisNode" select="."/>
<xsl:value-of select="$thisNode/#*[name()=current()/#Name]" disable-output-escaping="yes" />
</xsl:template>
currently the view displays the data inside a table cell as:
Task 1; Task 2; Task 3;
I would like it to display as
Task 1
Task 2
Task 3
I've spent plenty of hours searching online but haven't found any solution that helps me so far.

What you could do is have a recursive template that converts semi-colons to <br /> tags, like so:
<xsl:template name="CharToLineBreak">
<xsl:param name="text" />
<xsl:param name="char" />
<xsl:choose>
<xsl:when test="contains($text, $char)">
<xsl:value-of select="substring-before($text, $char)" />
<br />
<xsl:call-template name="CharToLineBreak">
<xsl:with-param name="text" select="substring-after($text, $char)" />
<xsl:with-param name="char" select="$char" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
Then, instead of doing xsl:value-of as shown in your question, do xsl:call-template like so...
<xsl:call-template name="CharToLineBreak">
<xsl:with-param name="text" select="$thisNode/#*[name()=current()/#Name]" />
<xsl:with-param name="char" select="';'" />
</xsl:call-template>
I am not sure why you have so much complexity with getting the attribute value though. It could be simplified to just this
<xsl:call-template name="CharToLineBreak">
<xsl:with-param name="text" select="#Project_x0020_Tasks" />
<xsl:with-param name="char" select="';'" />
</xsl:call-template>
