问题

我有一组adoc文档，我正在将它们转换为markdown格式。对于大多数文档，我已经成功地进行了转换：

``` sh
asciidoc -b docbook -o temp.xml <infile>
pandoc -f docbook -t markdown_strict --atx-headers --mathjax temp.xml -o <outfile>

然后，我使用一些正则表达式来修复一些破损的图片链接并修复标题。然而，对于内联数学公式，这种方法不起作用。在adoc中，它们的语法是：latexmath:[$some_equation_here$]，有时多行公式中没有美元符号。

当这些公式转换为DocBook XML时，它们被保留并且格式如下：

<inlineequation>
<alt><![CDATA[$some_equation_here$]]></alt>
<inlinemediaobject><textobject><phrase></phrase></textobject></inlinemediaobject>
</inlineequation>

但是当pandoc将其转换回markdown时，它忽略了这些xml块。在pandoc转换过程中，如何保持markdown可读的公式格式($some_equation_here$)呢？mathjax扩展似乎无法解决这个问题。

我尝试使用单独的Python正则表达式，使用 re.sub(r'latexmath:\[\$?(.*?)\$?\]', r'$\g<1>$', file_contents) 来保留$，但结果是一些双重转义的文本，然后必须手动修复，而且有时会产生额外的/sup标签。尝试在XML文件中进行类似操作也产生了类似的结果。

I have a group of adoc documents that I&#39;m converting to markdown. For most of them I&#39;ve been able to convert them with:

``` sh
asciidoc -b docbook -o temp.xml &lt;infile&gt;
pandoc -f docbook -t markdown_strict --atx-headers --mathjax temp.xml -o &lt;outfile&gt;

followed by some regex to clean up some broken image links and fix the headers. However, this doesn't work for the in-line math equations. In the adoc they are in the syntax: latexmath:[$some_equation_here$] sometimes without the dollar signs for multi-line equations.

when this gets turned into the DocBook XML it seems to be preserved and is of the format:

<inlineequation>
<alt><![CDATA[$some_equation_here$]]></alt>
<inlinemediaobject><textobject><phrase></phrase></textobject></inlinemediaobject>
</inlineequation>

but when pandoc converts it back to markdown it ignores these blocks of xml. How can i keep it in a markdown readable equation ($some_equation_here$) format during the pandoc conversion? The mathjax extension doesn't seem to be helping with this operation.

I tried to use a seperate python regex that would use re.sub(r'latexmath:\[\$?(.*?)\$?\]', r'$\g<1>$', file_contents to keep the $ but it results in some double escaped text that then has to go be fixed manually as well as not fully working sometimes giving some extra /sup tags. Trying to do something similar with the XML file resulted in similar results.

Here is the translated content:

根据 pandoc 代码，DocBook 阅读器期望公式位于 <inlineequation> 元素下的 <mathphrase> 元素中。因此，只需将 <alt> 标签替换为 <mathphrase> 即可使 pandoc 捕捉到公式。一般情况下，这会生成无效的 DocBook XML，因为 <inlineequation> 应该包含 要么 <mathphrase> 要么 <inlinemediaobjects>，但这对 pandoc 并不重要。

注意，pandoc 会自己插入美元符号，所以这些也应该被移除。上述命令使用 Lua 过滤器 来移除美元符号；unwrap-math.lua 包含以下内容：

function Math (mth)
  mth.text = mth.text:gsub('^%$', ''):gsub('%$$', '')
  return mth
end

cat << EOF | pandoc --from=docbook --to markdown --lua-filter=unwrap-math.lua
<para>
  <inlineequation>
    <mathphrase><![CDATA[$some_equation_here$]]></mathphrase>
    <inlinemediaobject><textobject><phrase></phrase></textobject></inlinemediaobject>
  </inlineequation>
</para>
EOF
$some_equation_here$

function Math (mth)
  mth.text = mth.text:gsub('^%$', ''):gsub('%$$', '')
  return mth
end
