Re: Adding elements to unknown tree structure

Please try this stylesheet (tested with Saxon 8.5.1)

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="xml" indent="yes" />

<xsl:param name="folder_name" />
<xsl:param name="path2folder" />

<xsl:template match="node() | @*">
   <xsl:copy>
     <xsl:apply-templates select="node() | @*" />
   </xsl:copy>
</xsl:template>

<xsl:template match="folder">
   <xsl:variable name="temp">
     <xsl:call-template name="p2f">
       <xsl:with-param name="node" select="." />
       <xsl:with-param name="path" select="@name" />
     </xsl:call-template>
   </xsl:variable>
   <xsl:choose>
     <xsl:when test="$temp = $path2folder">
       <folder name="{@name}">
         <xsl:apply-templates />
         <folder name="{$folder_name}" />
       </folder>
     </xsl:when>
     <xsl:otherwise>
       <folder name="{@name}">
         <xsl:apply-templates />
       </folder>
     </xsl:otherwise>
   </xsl:choose>
</xsl:template>

<xsl:template name="p2f">
   <xsl:param name="node" />
   <xsl:param name="path" />

   <xsl:choose>
     <xsl:when test="$node/parent::folder">
       <xsl:call-template name="p2f">
         <xsl:with-param name="node" select="$node/parent::folder" />
         <xsl:with-param name="path"
select="concat($node/parent::folder/@name,'/',$path)" />
       </xsl:call-template>
     </xsl:when>
     <xsl:otherwise>
       <xsl:value-of select="$path" />
     </xsl:otherwise>
   </xsl:choose>
</xsl:template>

</xsl:stylesheet>

In this stylesheet I have not implemented your requirement
need to make sure that both "root" and "pictures" exist and if they
don't, create them first.

If you really need this to be done, I can try that. But it may take some
time..
