删除了嵌套表达式中的默认内容

Question

我正在使用Pyparsing模块和nestedExpr函数。你知道吗

我想给出一个定界符，而不是在nestedexpr函数的content参数中定界的默认空白。 如果我有下面这样的文字

text = "{{Infobox | birth_date = {{birth date and age|mf=yes|1981|1|31}}| birth_place = ((Memphis, Tennessee|Memphis)), ((Tennessee)), U.S.| instrument = ((Beatboxing)), guitar, keyboards, vocalsprint expr.parse| genre = ((Pop music|Pop)), ((contemporary R&B|R&B))| occupation = Actor, businessman, record producer, singer| years_active = 1992–present| label = ((Jive Records|Jive)), ((RCA Records|RCA)), ((Zomba Group of Companies|Zomba))| website = {{URL|xyz.com|Official website}} }}"

当我给出nestedExpr('{{','}}').parseString(text)时，我需要如下所示的输出：

['Infobox | birth_date =' ,['birth date and age|mf=yes|1981|1|31'],'| birth_place = ((Memphis, Tennessee|Memphis)), ((Tennessee)), U.S.| instrument = ((Beatboxing)), guitar, keyboards, vocalsprint expr.parse| genre = ((Pop music|Pop)), ((contemporary R&B|R&B))| occupation = Actor, businessman, record producer, singer| years_active = 1992–present| label = ((Jive Records|Jive)), ((RCA Records|RCA)), ((Zomba Group of Companies|Zomba))| website =',[ 'URL|xyz.com|Official website' ]]

如何将','或'|'作为delimiter而不是空格分隔的字符？我试着给他们角色，但没用。你知道吗
