When you talk of an element with no monogr/author, do you mean the monogr/author element is absent, or do you mean the element is present and its value is empty? Being present but empty would account for the results you are describing.

Subject: Re: [xsl] Integrated sort using different elements
Hi Ken,
Thanks for the tip. A bit earlier, I tried the
<xsl:sort select=" ( monogr/author, analytic/author, monogr/editor, monogr/title )[1]"/>
and it produced some kind of weird results. First it listed the ones with analytic/author but no monogr/author. Then the ones with a monogr/title, and no author anywhere. Then it alphabetized all the ones with monogr/author. (In my smaller test set, there didn't happen to be any editors.)
I'm not sure what's happening there, but when I did:
<xsl:sort select="concat(monogr[1]/author[1],
analytic[1]/author[1], monogr[1]/editor[1], monogr[1]/title[1])"/> ([1]'s because there's sometimes multiple editions with multiple authors)
it sorted everything the way I needed it. I'm not sure if the data happens to be such that the concat() problem you mentioned doesn't come up, but one way or another it works.
Thanks everyone for your help! This has really been a life saver.

Would it work to sort on the concatenation? -I think the sequence solution is safer than the
<xsl:sort select="concat(monogr/author, analytic/author, monogr/editor, monogr/title"/>
because if more than one field is present, then the initialcharactersof a following field, tacked on to the final characters ofa precedingfield, will but the record out of order.the result
Consider the following:
<biblStruct id="b1"> <monogr> <author>abc</author> ... <analytic> <author>xyz</author> ... <biblStruct id="b2"> <monogr> <author>abcdef</author>
Using the sequence approach would put "b1" before "b2" inbecause "abc" is before "abcdef", while using the concatenation approach would put "b2" before "b1" in the result because"abcdef" isbefore "abcxyz".neglected in your
I hope this illustrates an important issue that wasdecision.
