Question

I need to transform this structure

<A>
<B>value1</B>
</A>
<A>
<B>value2</B>
</A>

into

<A>
<B>value1<B>
<B>value2<B>
</A>

What is best solution using XSLT-1.0?
Thank you!

PS: I tried this code:

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.1" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> 
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>   
<xsl:key name="group_a" match="//A" use="B"/> 
<xsl:template match="/Test"> <a-node> <xsl:for-each select="//A"> <b-node> 
<xsl:value-of select="//A/B"/> </b-node> </xsl:for-each> </a-node> 
</xsl:template> 
</xsl:stylesheet> 

but it returns only first value:

<?xml version="1.0" encoding="utf-8"?> <a-node mlns:fo="http://www.w3.org/1999/XSL/Format"> <b-node>value1</b-node> <b-node>value1</b-node> </a-node> 

but I need:

<?xml version="1.0" encoding="utf-8"?> <a-node xmlns:fo="http://www.w3.org/1999/XSL/Format"> <b-node>value1</b-node> <b-node>value2</b-node> </a-node>

Since it seems you need to collapse all the children under a single node, then you don’t need the foreach on “A”, you can move directly to the “B” children

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">
    <xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
    <xsl:template match="/">
        <A>
            <xsl:for-each select="//A/B">
                <B>
                    <xsl:value-of select="./text()"/>
                </B>
            </xsl:for-each>
        </A>
    </xsl:template>
</xsl:stylesheet>
