That might be true in this case, but that suggests the specific example
involved a data entry error assuming the other areas truly need multiple
affiliations.

If it turned out that *all* cases of multiple affiliations were the same as
you identify, an especially easy way to deal with this would be to tweak
the output so that paper appeared before the authors (or alter the DTD so
it's an attribute of presentation). The output could then be generated with
a single line command that stripped the newlines with tr and piped that
output into sed. Though doing stuff like that via regex is not very eye
pleasing even it's fast and easy.

Re: [CODE4LIB] direct descendants of a given element

[Ellerbeck, Carol]

On the other hand, is it really a case of two affiliations, or just one?  The 
University of Maryland University College (UMUC) is an American public 
not-for-profit university located in Adelphi in Prince George's County, Maryland

I am using XSLT because may source is in XML. People are marking up plain text 
into XML with Oxygen. From within the Oxygen environment they can then execute 
the XSLT to create the tab-delimited files. Piping the XML to JSON (the “new 
XML”) would add complexity to the workflow. —Eric

And I’m seriously thinking about changing my DTD so affiliations reside inside 
a person element.

Howdy Eric,

Are you using XSLT because you need to, or is it because your source is in
XML? Also, do you have any environmental constraints?

The reason I ask is that converting that specific XML to the tab delimited
output you specify looks like it would be much easier via conversion to
JSON and filtered through jq than using XSLT.

Hi, Eric,

Here is more of a "push" approach (assuming you are able to use XSLT
2.0+)--which I highly recommend whenever working with XSLT.

Re: [CODE4LIB] direct descendants of a given element

[Ashley M. Clark]

Hi Eric,

Whew, this is a tangle! Getting the descendants of a given element is 
easy in XPath, and your nested  instructions should do the 
right thing. You could even combine the two instructions with this XPath:


    .//presentation//person

The difficulty you noted is that there's no hierarchy to explicitly 
connect any given person to their affiliation. For each person, you need 
to get the following elements named 'affiliation' that _do not_ occur 
after a following . This is not an easy XPath to write!


When I've run into this problem in the past, I've used a named XSLT 
template which takes the next X number of siblings and tests if they 
meet an inclusion criteria (here, "am I an ?" or 
`exists(self::affiliation)` ). Everything after the first non-match is 
thrown out.


However, this is not a method I'd recommend to anyone, because it turns 
out there's a somewhat easier method using :


   
  
  
  
  
  
    Working on 
    
     of 
    
  

  
  
  
    


I found out about this method in Michael Kay's excellent _XSLT 2.0 and 
XPath 2.0_. It forms a group of all sibling elements that occur after 
, but before the next . You can then use the 
`current-group()` function to get the sequence of elements that for sure 
are associated with this particular person, and tests on the self axis 
to narrow _those_ down to only the elements of a certain type. I added 
some special sauce with the `string-join()` function to put a '|' 
between each affiliation for a given person.


Hope this helps!

Best,
Ashley

[CODE4LIB] direct descendants of a given element

How can I use XSLT to find the direct descendants of a given element with a 
given name?

I want to create a tab-delimited version of an XML file. I have the following 
XML snippet, and notice how each of the persons in the first presentation have 
a single affiliation, but the person of the second presentation has two 
affiliations:

  

  RICHARD G. ANDERSON
  Lindenwood University
  AREERAT KICHKHA
  Lindenwood University
  Is Less More?


  BRIAN W. SLOBODA
  University of Maryland
  University College
  Inflation Policies

  

I want my resulting tab-delimited file to look like this:

  RICHARD G. ANDERSON  Lindenwood University  Is Less More?
  AREERAT KICHKHA  Lindenwood University  Is Less More?
  BRIAN W. SLOBODA University of Maryland|University College  Inflation 
Policies

I have the following XSLT snippet, but my process of getting affiliations is 
not nearly correct:

  

  
  
  

  

Can you offer any suggestions? What sort of XPath expression should I be using 
to find all of the affiliation elements between person elements? Something with 
following-sibling?
