每个条目都以条目号开头，后跟一个或多个空白字符，最后是按换行符分割的描述性文本。

iXML语法

\n

data: entry+ .\nentry: -#a, entrynum, " "+, content .\nentrynum: -digit+ .\ndigit: ["1"-"9"] .\ncontent: ~[]+; -#a+ .\n

\n

对 iXML 语法的初步尝试产生了不明确的解析（使用CoffeePot iXML 处理器）。

首先，我想了解如何对条目进行分块，然后开始解析内容：例如，每个条目编号后跟一个或多个空格，然后是字母数字标题，后跟句点等。

Answer 1

“或许。” iXML 的一大优势是它可以处理歧义。这使得语法变得非常非常容易编写。如果模棱两可的选择同样有效，或者如果您不关心选择哪个模棱两可的选择，那么它的效果就非常好。

对于书目数据，我怀疑某些选择比其他选择更有效，并且您确实关心选择哪个选项，这使得它变得更加困难。我还敢打赌，由于 OCR 不完善，因此存在很多歧义。

我不认为单个 iXML 语法能够解析输入并准确生成您想要的输出，但它可能构成某些更广泛策略的有用部分。我首先尝试将参考书目分成单独的条目，将语法限制为单个条目。然后我可能会看看是否可以制定出不同类别的条目（书籍、杂志、期刊等），并且每个类别都有不同的语法。

祝你好运！
