FOP XSL 1.0 Replace text and keep line break - xslt

Question

I'm trying to generate a pdf using xsl + xml, but Im having problems on a part of the document where there is some lines of text with line breaks.
When generating the document it did not keep those line breaks.
I have tried everything, and Im completely stuck.
My code is:
<fo:table-row>
<fo:table-cell margin-right="0mm" margin-left="0mm"
margin-bottom="0mm" margin-top="0mm"
xsl:use-attribute-sets="bordergris" number-columns-spanned="5">
<fo:block xsl:use-attribute-sets="titoldades"
space-before.optimum="0pt" space-after.optimum="0pt"
keep-together="always" >
More info:
</fo:block>
<fo:block xsl:use-attribute-sets="dades"
space-before.optimum="0pt" space-after.optimum="0pt"
keep-together="always" linefeed-treatment="preserve">
<xsl:call-template name="replace-string">
<xsl:with-param name="text" select="/Response/DataList/Data/MoreInfo"/>
<xsl:with-param name="replace" select="' '" />
<xsl:with-param name="with" select="'<fo:block/>'"/>
</xsl:call-template>
</fo:block>
</fo:table-cell>
</fo:table-row>
Which use a template function:
<xsl:template name="replace-string">
<xsl:param name="text"/>
<xsl:param name="replace"/>
<xsl:param name="with"/>
<xsl:choose>
<xsl:when test="contains($text,$replace)">
<xsl:value-of select="substring-before($text,$replace)"/>
<xsl:value-of select="$with"/>
<xsl:call-template name="replace-string">
<xsl:with-param name="text"
select="substring-after($text,$replace)"/>
<xsl:with-param name="replace" select="$replace"/>
<xsl:with-param name="with" select="$with"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
And the resulting text appears with the hardcoded text "<fo:block/>" instead of applying the line break.
What am I doing wrong?
Thanks!!!

The important thing is to put the following properties inside the fo:block:
inefeed-treatment="preserve" white-space-collapse="false" white-space-treatment="preserve"
And then do the replace with the following:
<fo:block xsl:use-attribute-sets="dades"
linefeed-treatment="preserve" white-space-collapse="false" white-space-treatment="preserve">
<xsl:call-template name="replace-string">
<xsl:with-param name="text" select="/Response/DataList/Data/MoreInfo"/>
<xsl:with-param name="replace" select="' '" />
<xsl:with-param name="with" select="'
'"/>
</xsl:call-template>
