I have the following XML (docbook):
My goal is to produce:

    <entry one="ABC" two="DEF 2"/>

In C/C++ this is trivial at each step whenever row/entry is empty I
would use some local variable instead. But in XSL I am stuck with:

                <xsl:for-each select="row">
                  <xsl:variable name="one"
select="normalize-space(string-join(entry[1]/para,' '))"/>
                  <xsl:variable name="two"
select="normalize-space(string-join(entry[2]/para,' '))"/>
                  <entry one="{$one}" two="{$two}"/>

Could someone please let me know what the correct solution is when using XSL ?

Solution or syntax?

An abbreviated syntax for what you have would be:

 <xsl:for-each select="row">
   <entry one="{normalize-space(string-join(entry[1]/para,' '))}"
          two="{normalize-space(string-join(entry[2]/para,' '))}"/>

But whether or not this is a correct solution depends on whether or not the function calls you chose have met your requirements.

You were almost there when using the braces for the attribute value template ... but *any* expression can go in an attribute value template, not just a variable reference.

I hope this helps.
