Hi,
I'm new on XSL an XPATH, I'm trying to create an xsl tranformation to do that:

XML to transform

<test id="a">
<leaf attribute="1">some text</leaf>
</test>

Result Wanted:
<test id="a">
<leaf>
<attribute>1</attribute>
<leaf> some text</leaf>
</leaf>
</test>

The XSL transformation:

If a tag (element) has an attribute, and text value:
Example: <leaf attribute="1">some text</leaf>

convert the attribute to an element, and add a child node with the same name as the element:
<leaf>
<attribute>1</attribute> // attribute converted to an element
<leaf> some text</leaf> // a new sub-element with the same name as the containing element
</leaf>

But if a tag with an attribute has no text-element:
Example: the "test" element
<test id="a">
<leaf>
...
</leaf>
</test>

Do nothing.

This should get you started
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:template match="*[string-length(normalize-space(text())) > 0]">
        <xsl:copy>
            <xsl:for-each select="@*">
                <xsl:element name="{name()}">
                    <xsl:value-of select="."/>
                </xsl:element>
            </xsl:for-each>
            <xsl:element name="{name()}">
                <xsl:apply-templates select="node()"/>
            </xsl:element>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="*[string-length(normalize-space(text())) = 0]">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates select="node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

Thanks Gertone, but this is not the result expect:

Input XML:

<test>blabla</test>

Result:

<test><test>blabla</test></test>

Result expected:

<test>blabla</test>

Here the "test" tag doesn't have any attribute, so It should remain the same.

ok, minor fix
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:template match="*[string-length(normalize-space(text())) > 0][@*]">
        <xsl:copy>
            <xsl:for-each select="@*">
                <xsl:element name="{name()}">
                    <xsl:value-of select="."/>
                </xsl:element>
            </xsl:for-each>
            <xsl:element name="{name()}">
                <xsl:apply-templates select="node()"/>
            </xsl:element>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node()">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates select="node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>
