XSL list:
I'm developing a stylesheet that converts XML to html to display research
articles. The articles contains three citation types, bibliographical, table
call, and figure call. Upon encountering a table call or figure call, I would
like to display the table or figure referred to immediately following the
paragraph that contains the call. I want the table or figure to appear in the
order they were referred to in the paragraph and I want each table or figure to
only appear once in the outputted document. Tables and figures are numbered in
order of their reference, though at any point you can refer to a table or
figure that has been previously called.
Citations look like this:
<xref ref-type="bibr" rid="B1">1</xref>
<xref ref-type="table" rid="T1">Table 1</xref>
<xref ref-type="fig" rid="F1">Figure 1</xref>
Sample Input:
[A paragraph that includes a citation for Table 1.]
[A paragraph that includes citations for Table 2, Table 1, Figure 1, and Table
3.]
Sample Output:
[A paragraph that includes a citation for Table 1.]
Table 1
[A paragraph that includes citations for Table 2, Table 1, Figure 1, and Table
3.]
Table 2
Figure 1
Table 3
My initial thought is to create a set of keys:
Key: Last Table Processed
Key: Last Figure Processed
Key: Last Table Encountered
Key: Last Figure Encountered
Since the tables and figures are numbered in order, a comparison of the two
keys should be in order. This comparison should be made at the end of
processing a paragraph. However, I'm not quite sure how I'd make such a
comparison or even if I can use keys in that manner. I'm thinking I might need
to generate some sort of array to keep track of the multiple citations
encountered so that in the sample provided the output is (Table 2, Figure 1,
Table 3) and not (Table 2, Table 3, Figure 1) or (Figure 1, Table 2, Table 3).
If I were to build an array, since at this point I don't need to process <xref>
citations of "bibr" type, those should be ignored. Any suggestions would be
greatly appreciated. Thanks.
