|---|
| 22 | Richard Mahoney (for providing a test case) |
|---|
| 23 | |
|---|
| 24 | Editted by Sara Sprenkle to be more robust and handle more bibtex features. |
|---|
| 25 | (c) 2003-01-15 |
|---|
| 26 | |
|---|
| 27 | 1. Changed bibtex: tags to bibxml: tags. |
|---|
| 28 | 2. Use xmlns:bibxml="http://bibtexml.sf.net/" |
|---|
| 29 | 3. Allow spaces between @type and first { |
|---|
| 30 | 4. "author" fields with multiple authors split by " and " |
|---|
| 31 | are put in separate xml "bibxml:author" tags. |
|---|
| 32 | 5. Option for Titles: words are capitalized |
|---|
| 33 | only if first letter in title or capitalized inside braces |
|---|
| 34 | 6. Removes braces from within field values |
|---|
| 35 | 7. Ignores comments in bibtex file (including @comment{ or % ) |
|---|
| 36 | 8. Replaces some special latex tags, e.g., replaces ~ with ' ' |
|---|
| 37 | 9. Handles bibtex @string abbreviations |
|---|
| 38 | --> includes bibtex's default abbreviations for months |
|---|
| 39 | --> does concatenation of abbr # " more " and " more " # abbr |
|---|
| 40 | 10. Handles @type( ... ) or @type{ ... } |
|---|
| 41 | 11. The keywords field is split on , or ; and put into separate xml |
|---|
| 42 | "bibxml:keywords" tags |
|---|
| 43 | 12. Ignores @preamble |
|---|
| 44 | |
|---|
| 45 | Known Limitations |
|---|
| 46 | 1. Does not transform Latex encoding like math mode and special |
|---|
| 47 | latex symbols. |
|---|
| 48 | 2. Does not parse author fields into first and last names. |
|---|
| 49 | E.g., It does not do anything special to an author whose name is |
|---|
| 50 | in the form LAST_NAME, FIRST_NAME |
|---|
| 51 | In "author" tag, will show up as |
|---|
| 52 | <bibxml:author>LAST_NAME, FIRST_NAME</bibxml:author> |
|---|
| 53 | 3. Does not handle "crossref" fields other than to print |
|---|
| 54 | <bibxml:crossref>...</bibxml:crossref> |
|---|
| 55 | 4. Does not inform user of the input's format errors. You just won't |
|---|
| 56 | be able to transform the file later with XSL |
|---|
| 57 | |
|---|
| 58 | You will have to manually edit the XML output if you need to handle |
|---|
| 59 | these (and unknown) limitations. |
