XSLT 1.0: escaping double quotes - xslt

Question

I have a XML file following this scheme:
<translationData>
<product>
<attributeValue>
<value>1/4"</value>
<value1>1/4"</value1>
<currentValue>aaaa;bbbb</currentValue>
</attributeValue>
</product>
</translationData>
because of the semicolon in "currentValue" i need to escape the semicolon AND the double quotes in "value".
I am able to escape the semicolon by placing all text in qoutes as following:
XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="utf-8" />
<xsl:param name="delim" select="';'" />
<xsl:param name="quote" select="'"'" />
<xsl:param name="break" select="'
'" />
<xsl:template match="/">
<xsl:apply-templates select="translationData/product/attributeValue" />
</xsl:template>
<xsl:template match="attributeValue">
<xsl:apply-templates />
<xsl:if test="following::*">
<xsl:value-of select="$break" />
</xsl:if>
</xsl:template>
<xsl:template match="*">
<!-- remove normalize-space() if you want keep white-space at it is -->
<xsl:value-of select="concat($quote, translate(.,'"','\"'), $quote)" />
<xsl:if test="following-sibling::*">
<xsl:value-of select="$delim" />
</xsl:if>
</xsl:template>
<xsl:template match="text()" />
</xsl:stylesheet>
but somehow the Output is:
"1/4\";"1/4\";"aaaa;bbbb"
instead of
"1/4\"";"1/4\"";"aaaa;bbbb"
Where am I going wrong?
I am new to XML and XSLT and did not find any question handling this specific case.
XSLT code is from an answer by #Tomalak for another question. see here

The translate() function will only replace each single character with another single character.
To replace a single character " with a two-character string\" you need to use a named recursive template or - if your processor supports it - an extension function such as EXSLT str:replace().
Here's an example of using a recursive template:
...
<xsl:template match="*">
<xsl:text>"</xsl:text>
<xsl:call-template name="replace">
<xsl:with-param name="text" select="."/>
</xsl:call-template>
<xsl:text>"</xsl:text>
<xsl:if test="position()!=last()">
<xsl:text>;</xsl:text>
</xsl:if>
</xsl:template>
...
<xsl:template name="replace">
<xsl:param name="text"/>
<xsl:param name="searchString">"</xsl:param>
<xsl:param name="replaceString">\"</xsl:param>
<xsl:choose>
<xsl:when test="contains($text,$searchString)">
<xsl:value-of select="substring-before($text,$searchString)"/>
<xsl:value-of select="$replaceString"/>
<!-- recursive call -->
<xsl:call-template name="replace">
<xsl:with-param name="text" select="substring-after($text,$searchString)"/>
<xsl:with-param name="searchString" select="$searchString"/>
<xsl:with-param name="replaceString" select="$replaceString"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
