Moving attribute name

Hi!
I'm working on a big XML document that I need to change slightly. I think it can be done with XSLT but I can't figure out how. The document is full of tags like these:

HTML Code:

---

<verse value="1" chapter="1">...some text...</verse>

---

I need to extract the numbers of the 'value' and 'chapter' attributes to add them in the text and style them separately. Something like this:

HTML Code:

---

<verse>
<chapter>1</chapter>
<value>1</value>
...some text...
</verse>

---

Can this be done with XSLT or is some other script solution better? I don't know XSLT and I tried to learn it just to solve this problem but I'm not doing very well. This is my attempt so far:

HTML Code:

---

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fn="http://www.w3.org/2005/xpath-functions">

<xsl:template match="verse[@value]">
        <xsl:value-of select="verse[@value]"/><xsl:apply-templates/>
</xsl:template>

</xsl:stylesheet>

---

I've made some progress and this is the code I have now:

HTML Code:

---

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
    <book>
        <xsl:apply-templates/>
    </book>
</xsl:template>

<xsl:template match="verse">
    <xsl:if test="@value = 1">
            <chapter-number><xsl:value-of select="@chapter"/></chapter-number>
    </xsl:if>
    <verse-number><xsl:value-of select="@value"/></verse-number>
    <xsl:apply-templates/>
</xsl:template>

</xsl:stylesheet>

It does the job but the problem is that it removes all tags other than ones explicitly written in my code. How can I keep all the tags from the original file and just rebuild the <verse> tags according to my code?
