TEI output error (CollateX Python 2.2)

[djbpitt]

Given:

%reload_ext autoreload
%autoreload 2
from collatex import *
collation = Collation()
collation.add_plain_witness("A","The big gray koala.")
collation.add_plain_witness("B", "The big gray koala.")
collation.add_plain_witness("C","The gray fuzzy koala lives in a tree.")
table = collate(collation)
print(table)

table alignment is correct:

+---+-----+-----+------+-------+-------+-----------------+---+
| A | The | big | gray | -     | koala | -               | . |
| B | The | big | gray | -     | koala | -               | . |
| C | The | -   | gray | fuzzy | koala | lives in a tree | . |
+---+-----+-----+------+-------+-------+-----------------+---+

but TEI alignment doesn’t recognize that all instances of “koala” agree. When we run:

tei = collate(collation, output="tei", indent=True)
print(tei)

we get:

<?xml version="1.0" ?>
<cx:apparatus xmlns="http://www.tei-c.org/ns/1.0" xmlns:cx="http://interedition.eu/collatex/ns/1.0">
	The 
	<app>
		<rdg wit="#A #B">big</rdg>
		<rdg wit="#C"/>
	</app>
	 
	gray 
	<app>
		<rdg wit="#C">fuzzy</rdg>
		<rdg wit="#A #B"/>
	</app>
	 
	<app>
		<rdg wit="#A #B">koala</rdg>
		<rdg wit="#C">koala</rdg>
	</app>
	 
	<app>
		<rdg wit="#C">lives in a tree</rdg>
		<rdg wit="#A #B"/>
	</app>
	.
</cx:apparatus>

The “koala” readings all agree, and therefore should be output as plain text, and not inside a <rdg>.

Furthermore, there should not be two <rdg> children of the same <app> that have the same textual content. If we add another witness to remove the exact equality:

%reload_ext autoreload
%autoreload 2
from collatex import *
collation = Collation()
collation.add_plain_witness("A","The big gray koala.")
collation.add_plain_witness("B", "The big gray koala.")
collation.add_plain_witness("D", "The big gray wombat.")
collation.add_plain_witness("C","The gray fuzzy koala lives in a tree.")
table = collate(collation,segmentation=False, near_match=True)
print(table)

The table output is again correct:

+---+-----+-----+------+-------+--------+-------+----+---+------+---+
| A | The | big | gray | -     | koala  | -     | -  | - | -    | . |
| B | The | big | gray | -     | koala  | -     | -  | - | -    | . |
| D | The | big | gray | -     | wombat | -     | -  | - | -    | . |
| C | The | -   | gray | fuzzy | koala  | lives | in | a | tree | . |
+---+-----+-----+------+-------+--------+-------+----+---+------+---+

but the TEI output incorrectly puts the koalas in different <rdg> elements, so that:

tei = collate(collation, output="tei", indent=True, segmentation=False, near_match=True)
print(tei)

outputs:

<?xml version="1.0" ?>
<cx:apparatus xmlns="http://www.tei-c.org/ns/1.0" xmlns:cx="http://interedition.eu/collatex/ns/1.0">
	The 
	<app>
		<rdg wit="#A #B #D">big</rdg>
		<rdg wit="#C"/>
	</app>
	 
	gray 
	<app>
		<rdg wit="#C">fuzzy</rdg>
		<rdg wit="#A #B #D"/>
	</app>
	 
	<app>
		<rdg wit="#A #B">koala</rdg>
		<rdg wit="#C">koala</rdg>
		<rdg wit="#D">wombat</rdg>
	</app>
	 
	<app>
		<rdg wit="#C">lives</rdg>
		<rdg wit="#A #B #D"/>
	</app>
	 
	<app>
		<rdg wit="#C">in</rdg>
		<rdg wit="#A #B #D"/>
	</app>
	 
	<app>
		<rdg wit="#C">a</rdg>
		<rdg wit="#A #B #D"/>
	</app>
	 
	<app>
		<rdg wit="#C">tree</rdg>
		<rdg wit="#A #B #D"/>
	</app>
	.
</cx:apparatus>

These may be consequences of a single problem, the failure to recognize that the koalas belong together.
