XSLT1 fo replacing placeholders
Question
I have to replace some placeholder like $$RUOLO^ with a xpath, this is the result xsl:fo:
<fo:block>e per il ruolo $$RUOLO^ , funzione <xsl:value-of xmlns:xsl="http://www.w3.org/1999/XSL/Transform" select="/root/ddx[@id='rsSelect']/r/FUNZIONE_BREVE"/> da lei ricoperta per la specifica informazione con la seguente motivazione $$DESCRIZIONE_ISCRIZIONE^ .</fo:block>
I have replaced $$FUNZIONE^ with select="/root/ddx[@id='rsSelect']/r/FUNZIONE_BREVE"/> but this dosent happen for RUOLO. Why not?
This is like I do:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

I use this template only, like the last of chain substitutions (pipeline). Why doens't get the same expected for RUOLO and DESCRIZIONE_ISCRIZIONE?
Thanks

Thanks @JLRishe It works for replacing but, it doesn't consider the so all text appear in the same line without CARRIAGE RETURN preservation.. XSL FO Input look likes:

The problem here is that when applying templates to nodes, a single node can only be matched by one template. Since your template for FUNZIONE has a higher precedence than the one for RUOLO or DESCRIZIONE_ISCRIZIONE (because it appears later than them), that is the one that is being used.
The solution is to use a recursive approach that progressively replaces placeholders until there are no more to replace. The following does this and also eliminates a lot of the duplication in your XSLT:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format" exclude-result-prefixes="fo vr"
xmlns:vr="my-variables"
>
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
<vr:substitutions>
<substitution key="$$FUNZIONE^" path="/root/ddx[@id='rsSelect']/r/FUNZIONE_BREVE" />
<substitution key="$$RUOLO^" path="/root/ddx[@id='rsSelect']/r/RUOLO_BREVE" />
<substitution key="$$CODICE_INFORMAZIONE^" path="/root/ddx[@id='rsSelect']/r/CODICE_INFORMAZIONE" />
<substitution key="$$DESCRIZIONE_ISCRIZIONE^" path="/root/ddx[@id='rsSelect']/r/DESCRIZIONE_ISCRIZIONE" />
</vr:substitutions>
<xsl:variable name="substitutions" select="document('')/*/vr:substitutions/substitution" />
<!-- Identity template -->
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="fo:block[contains(., '$$')] | fo:inline[contains(., '$$')]">
<fo:block>
<xsl:call-template name="PerformSubstitutions">
<xsl:with-param name="text" select="." />
</xsl:call-template>
</fo:block>
</xsl:template>
<xsl:template name="PerformSubstitutions">
<xsl:param name="text" />
<xsl:variable name="substitution" select="$substitutions[contains($text, @key)]" />
<xsl:choose>
<xsl:when test="$substitution">
<!-- Recursively call PerformSubstitutions on portion before placeholder-->
<xsl:call-template name="PerformSubstitutions">
<xsl:with-param name="text" select="substring-before($text, $substitution/@key)" />
</xsl:call-template>
<!-- Insert xsl:value-of -->
<xsl:element name="xsl:value-of">
<xsl:attribute name="select">
<xsl:value-of select="$substitution/@path"/>
</xsl:attribute>
</xsl:element>
<!-- Recursively call PerformSubstitutions on portion after placeholder-->
<xsl:call-template name="PerformSubstitutions">
<xsl:with-param name="text" select="substring-after($text, $substitution/@key)" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<!-- No substitutions found. Just output the text -->
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
You can handle as many placeholders as you need by adding more elements to the <vr:substitutions> section.
When run on this input XML:
<n xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<fo:inline>Some text $$FUNZIONE^ and $$RUOLO^ other text $$DESCRIZIONE_ISCRIZIONE^ </fo:inline>
<fo:block>Some more text $$CODICE_INFORMAZIONE^ yay.</fo:block>
</n>
The output is:
<n xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<fo:block>Some text <xsl:value-of select="/root/ddx[@id='rsSelect']/r/FUNZIONE_BREVE" /> and <xsl:value-of select="/root/ddx[@id='rsSelect']/r/RUOLO_BREVE" /> other text <xsl:value-of select="/root/ddx[@id='rsSelect']/r/DESCRIZIONE_ISCRIZIONE" /> </fo:block>
<fo:block>Some more text <xsl:value-of select="/root/ddx[@id='rsSelect']/r/CODICE_INFORMAZIONE" /> yay.</fo:block>
