Subject: [xsl] Displaying Code Dependent on First Encounter of Specific Reference From: "Joe Heidenreich" <HeidenreichJ@xxxxxxxx> Date: Wed, 13 Oct 2004 16:57:37 -0400 |
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. > - Joe
