在dired中查找并替换为无正则表达式

Question

我试图将网站转换为电子书，并且在每个要删除的页面的开头都有一大块html。正如你可以想象的那样，使用Q导致没有匹配，因为大块中的某些内容没有正确转义。当我尝试将问题解决时，我得到堆栈溢出。

我真正需要的是找到并替换而不使用正则表达式的方式，采用通常的M-％方式。这可能吗？

理论上，正则表达式的行为是可选的，但函数调用有问题的硬编码假设在一些地方。我认为最简单的解决方案是制作拷贝，它们在运行时不会设置正则表达式标志。

(eval-after-load 'dired 
    '(define-key dired-mode-map (kbd "C-c Q") 'my-dired-do-query-replace)) 

(defun my-dired-do-query-replace (from to &optional delimited) 
    "Do `query-replace' of FROM with TO, on all marked files. 
Third arg DELIMITED (prefix arg) means replace only word-delimited matches. 
If you exit (\\[keyboard-quit], RET or q), you can resume the query replace 
with the command \\[tags-loop-continue]." 
    (interactive 
    (let ((common 
      (query-replace-read-args 
      "Query replace in marked files" nil t))) 
    (list (nth 0 common) (nth 1 common) (nth 2 common)))) 
    (require 'dired-aux) 
    (dolist (file (dired-get-marked-files nil nil 'dired-nondirectory-p)) 
    (let ((buffer (get-file-buffer file))) 
     (if (and buffer (with-current-buffer buffer 
         buffer-read-only)) 
      (error "File `%s' is visited read-only" file)))) 
    (my-tags-query-replace 
    from to delimited '(dired-get-marked-files nil nil 'dired-nondirectory-p))) 

(defun my-tags-query-replace (from to &optional delimited file-list-form) 
    "Do `query-replace' of FROM with TO on all files listed in tags table. 
Third arg DELIMITED (prefix arg) means replace only word-delimited matches. 
If you exit (\\[keyboard-quit], RET or q), you can resume the query replace 
with the command \\[tags-loop-continue]. 
Fourth arg FILE-LIST-FORM non-nil means initialize the replacement loop. 
Fifth and sixth arguments START and END are accepted, for compatibility 
with `query-replace', and ignored. 

If FILE-LIST-FORM is non-nil, it is a form to evaluate to 
produce the list of files to search.
