applescript如何删除“\”；在变量中从我的文本中删除

好的，我有一个代码，在我问了一个问题后，从Wolfram alpha获取文本，创建URL并将其存储在变量“answer”中，但是它在文本中混合了/符号，系统因此发音错误。如何从变量中删除所有\符号

tell application "Safari"
    quit
end tell

set defaultAnswer to ""
set cancelButton to "Cancel"
set buttonResearch to "ReSearch"

display dialog "Query: " default answer defaultAnswer buttons {cancelButton, buttonResearch} default button buttonResearch cancel button cancelButton with icon 1
copy the result as list to {button_pressed, text_returned}

tell application "Dragon Dictate"
    set listening to false
end tell


if (button_pressed is buttonResearch) and (text_returned is not "") then
    set a to "http://www.wolframalpha.com/input/?i="
    set b to encode_text(text_returned, true, false)
    set c to a & b

    tell application "Safari"
        activate
        open
    end tell
    repeat
        if application "Safari" is running then exit repeat
    end repeat
    delay 1
    tell application "System Events" to tell process "Safari" to set visible to false
    tell application "Safari"
        tell window 1
            set current tab to (make new tab with properties {URL:c})
        end tell
    end tell
end if

say "let me look that up for you now"
delay 6

tell application "Safari" to set theString to (source of document 1)

(* Strip the text and only return the last line*)
set input to do shell script "echo " & (quoted form of theString) & "|sed -n \"/stringified/,/mInput/p\" | sed '$!N;$!D'"



global answer

set offSet1 to "\"stringified\": \""
set offSet2 to "\",\"mInput\""


my strip(offSet1, offSet2, input)

set mywordcount to count of words of answer

if mywordcount is greater than 50 then
    display dialog x
else


end if

tell application "Safari"
    quit
end tell

tell application "Dragon Dictate"
    set listening to true
end tell

on strip(offSet1, offSet2, thedata)
    (* Use the offsets of the pattens to match the text # thru # *)
    set textNumber1 to (offset of offSet1 in thedata)
    set theData1 to text -1 thru (textNumber1 + (count of offSet1)) of thedata
    set textNumber2 to (offset of offSet2 in theData1)
    set textString2 to text from word 1 to (textNumber2 - 1) of theData1
    set thedata to theData1
    set answer to textString2
end strip

你能用/symbols来分享一个变量值的例子吗？42（根据道格拉斯·亚当斯的幽默科幻小说《银河系漫游指南》），所以为了整合它，我将用answer替换s来实现，在你的脚本底部包含这个处理程序，然后在你调用“my strip（）”之后，你可以将答案设置为我的斜杠（答案）”
