Recursive XSLT generates text which doesn't match any template
Updating this post, to show where I'm currently at. So after some larification in my answer post, I'll update this post also with the current progress which is not so shiny. The XSLT stylesheet currently looks like the following:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="value" mode="values" />
<xsl:template match="value[@name = 'field_name' or @name = 'field_type' or @name = 'field_dim']" mode="values">
<xsl:element name="{@name}">
<xsl:value-of select="text()"/>
</xsl:element>
</xsl:template>
<xsl:template match="record[ancestor::record[@name='sig_in' or @name='sig_out'] and value[@name = 'field_name']]">
<xsl:param name="path" />
<xsl:variable name ="newpath">
<xsl:value-of select="concat($path,'/', value[@name = 'field_name' ]/text())" />
</xsl:variable>
<xsl:copy>
<xsl:attribute name="path">
<xsl:value-of select="$newpath" />
</xsl:attribute>
<xsl:apply-templates mode="values" select="value" />
<xsl:apply-templates>
<xsl:with-param name="path" select="$newpath" />
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

The Transformer is set to Xalan. In JAVA if I try to run this transformer I get the following exception:
[Fatal Error] :2:3: Content is not allowed in prolog.
While the code that does the actual transformation is the following:
private static Document tme(Document o) throws Exception {
StringWriter sw = new StringWriter();
StreamSource s = new StreamSource(
new StringReader("XSLT IN HERE as bare string copied from oxygen author"));
Transformer transformer = TransformerFactory.newInstance().newTransformer(s);
StreamResult res = new StreamResult(sw);
transformer.transform(new DOMSource(o.getDocumentElement()), res);
return DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader(sw.toString())));
}

Try something like this:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="value" mode="values"/>
<xsl:template match="value[@name = 'field_name' or
@name = 'field_type' or
@name = 'field_dim']" mode="values">
<xsl:element name="{@name}">
<xsl:value-of select="text()"/>
</xsl:element>
</xsl:template>
<xsl:template match="record[ ancestor::record[@name='sig_in' or @name='sig_out'] and
value[@name = 'field_name' ]]">
<xsl:param name="path" />
<xsl:variable name ="newpath">
<xsl:value-of select="concat($path,'/', value[@name = 'field_name' ]/text())" />
</xsl:variable>
<xsl:copy>
<xsl:attribute name="path">
<xsl:value-of select="$newpath"/>
</xsl:attribute>
<xsl:apply-templates mode="values" select="value"/>
<xsl:apply-templates >
<xsl:with-param name="path" select="$newpath" />
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
<xsl:template match="record[@name='sig_in']" >
<Inputs name="sig_in" >
<xsl:apply-templates >
<xsl:with-param name="path" select="'sig_in'" />
</xsl:apply-templates>
</Inputs>
</xsl:template>
<xsl:template match="record[@name='sig_out']" >
<Outputs name = "sig_out">
<xsl:apply-templates >
<xsl:with-param name="path" select="'sig_out'" />
</xsl:apply-templates>
</Outputs>
</xsl:template>
<xsl:template match="Values[descendant::record[@name='svc_sig'] ]">
<Values name="svc_sig">
<xsl:apply-templates select="descendant::record[@name='svc_sig']"/>
</Values>
</xsl:template>
<xsl:template match="node()">
<xsl:param name="path" />
<xsl:apply-templates select="node()" >
<xsl:with-param name="path" select="$path" />
</xsl:apply-templates>
</xsl:template>
</xsl:stylesheet>
Which will generate following output:
<?xml version="1.0"?>
<Values name="svc_sig">
<Inputs name="sig_in">
<record path="sig_in/docTest">
<field_name>docTest</field_name>
<field_type>record</field_type>
<field_dim>0</field_dim>
<record path="sig_in/docTest/doc.name">

<field_type>string</field_type>
<field_dim>0</field_dim>
</record>
</record>
<record path="sig_in/docListTest">
<field_name>docListTest</field_name>
<field_type>record</field_type>
<field_dim>1</field_dim>
<record path="sig_in/docListTest/d0">
<field_name>d0</field_name>
<field_type>record</field_type>
<field_dim>0</field_dim>
<record path="sig_in/docListTest/d0/d0.name">
<field_name>d0.name</field_name>
<field_type>string</field_type>
<field_dim>0</field_dim>
</record>
</record>
</record>
<record path="sig_in/packages_should_work">
<field_name>packages_should_work</field_name>
<field_type>recref</field_type>
<field_dim>0</field_dim>
</record>
<record path="sig_in/packages_list_should_work">
<field_name>packages_list_should_work</field_name>
<field_type>recref</field_type>
<field_dim>1</field_dim>
</record>
</Inputs>
<Outputs name="sig_out">
<record path="sig_out/doc">
<field_name>doc</field_name>
<field_type>string</field_type>
<field_dim>0</field_dim>
</record>
<record path="sig_out/lDoc">
<field_name>lDoc</field_name>
<field_type>string</field_type>
<field_dim>1</field_dim>
</record>
<record path="sig_out/docR">
<field_name>docR</field_name>
<field_type>string</field_type>
<field_dim>0</field_dim>
</record>
<record path="sig_out/lDocR">
<field_name>lDocR</field_name>
<field_type>string</field_type>
<field_dim>1</field_dim>
</record>
</Outputs>
</Values>
Attention: here are still two differences to your expected output (I did not find reasonable info how to build them):
* There is no field_dimension in output.
* Tow records are missing
<record path = "sig_in/packages_list_should_work/data:packages" />

It's not easy to tell if this is addressing the problem that you're describing, but in the middle of the above XSLT fragment,
<xsl:attribute name="name">
<xsl:value-of
select="concat($parent_node, '/', self::node[@name]/@name)" />
</xsl:attribute>
you could try changing the select attribute to:
select="concat($parent_node, '/', data)" />
That seems too obvious, so maybe I'm missing something.
