How to create an attribute node and attach it to output node..? - xslt

Question

I'm not able to figure out a way to attach an attribute node to output node in below scenario..
input xml:
<record>
<user>
<field name="LastName">user33</field>
<field name="FirstName">user33</field>
<field name="Title"/>
<field name="Email">user33#gmail.com</field>
<field name="WorkPhone"/>
<field name="Fax"/>
<field name="Description">new user</field>
<field name="Group Member"> group1</field>
</user>
</record>
Expected output:
<add class="user" id-val="user33 user33" >
<add-value attr="LastName">
<value type="string">user33</value>
</add-attr>
<add-value attr="FirstName">
<value type="string">user33</value>
</add-value>
<add-value attr="Email">
<value type="string">user33#gamil.com</value>
</add-value>
<add-value attr="Description">
<value type="string">new user</value>
</add-value>
</add>
this is the snippet of xslt that i have so far.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:variable name="lessThan" select="'<'"/>
<xsl:variable name="GreaterThan" select="'>'"/>
<xsl:template match="user">
<xsl:variable name="temp1" select="concat(field[#name=$srcdn-field-name1],' ')"/>
<xsl:variable name="temp2" select="concat($temp1,field[#name=$srcdn-field-name2])"/>
<xsl:variable name="src" select="translate($temp2,'+=,.\','-----')"/>
<xsl:value-of disable-output-escaping="yes" select="$lessThan"/>
<xsl:text>add</xsl:text>
<xsl:value-of disable-output-escaping="yes" select="$GreaterThan"/>
<!-- it is required to add attribute id-val to element <add> with value of $src-->
<xsl:for-each select="field[string()]">
<xsl:variable name="fieldValue" select="normalize-space(.)"/>
<xsl:choose>
<xsl:when test="#name !='Group Member'">
<add-value attr="{#name}">
<value type="string">
<xsl:value-of select="$fieldValue"/>
</value>
</add-value>
</xsl:when>
<xsl:otherwise>
<xsl:value-of disable-output-escaping="yes" select="$lessThan"/>
<xsl:text>/add</xsl:text>
<xsl:value-of disable-output-escaping="yes" select="$GreaterThan"/>
<!--perform some other operations-->
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Now my requirement is to have id-val and class as attributes of <add>.. In this context the <xsl:attribute> isn't working. What changes do i need to make to my xslt.?

You can't add an attribute to something that's not an element. That's one of the many reasons not to try to manually construct start and end tags. Try this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="user">
<xsl:variable name="temp1" select="concat(field[#name=$srcdn-field-name1],' ')"/>
<xsl:variable name="temp2" select="concat($temp1,field[#name=$srcdn-field-name2])"/>
<xsl:variable name="src" select="translate($temp2,'+=,.\','-----')"/>
<add class="user" id-val="{$src}">
<!-- it is required to add attribute id-val to element <add> with value of $src-->
<xsl:for-each select="field[string()]
[not((. | preceding-sibling::field)
[#name = 'Group Member'])]">
<add-value attr="{#name}">
<value type="string">
<xsl:value-of select="normalize-space()"/>
</value>
</add-value>
</xsl:for-each>
</add>
</xsl:template>
</xsl:stylesheet>
