我正在尝试解析已在 Automator 中转换为 TXT 文件的 HTML 文件。

我之前使用 Automator 从网站下载了 HTML 文件，现在我正在努力解析源代码。

最好，我只想获取表格的信息，并且需要对 1800 个不同的 HTML 文件重复此操作。

以下是源代码示例：

</head>
<body>
<div id="header">

我的 AppleScript 尝试text item delimiters以类似的方式提取表：

set p to input
set ex to extractBetween(p, "<table>", "</table>") -- extract the URL
to extractBetween(SearchText, startText, endText)
set tid to AppleScript's text item delimiters
set AppleScript's text item delimiters to startText
set endItems to text of text item -1 of SearchText
set AppleScript's text item delimiters to endText
set beginningToEnd to text of text item 1 of endItems
set AppleScript's text item delimiters to tid
return beginningToEnd
end extractBetween

如何从 HTML 文件中解析表格？

您可以通过 do javascript 命令在 Safari 中利用 HTML 解析器，而不是制作自己的 HTML 解析器。JavaScript 具有处理 HTML 元素和数据的内置功能。

此脚本仅获取页面中第一个表的 HTML：

tell application "Safari"
    tell document 1
        set theFirstTableHTML to do JavaScript "document.getElementsByTagName('table')[0].innerHTML"
    end tell
end tell

您可以使用此技术将基本的 DOM 脚本应用到任何页面并获取您想要读取的任何数据。您可以只获取表格单元格的值，或者任何您想要的值。

你真的很亲近。问题是您的 startText 变量。起始表格标记不在 html 文本中，因此无法找到。开始表格的行实际上是......

<table width="100%" border="0" cellspacing="0" cellpadding="0" id="profile-table">

因此，我修改了您的代码以分两步查找该标签。第一的...

<table

然后这个分开...

>

通过这种方式，我们可以忽略表格标签附带的所有代码（宽度、边框等），因为我认为它会因文件而异。这样做之后，我们只得到表的代码。试试这个...

set p to input
set ex to extractBetween(p, "<table", ">", "</table>")

to extractBetween(SearchText, startText1, startText2, endText)
    set tid to AppleScript's text item delimiters
    set AppleScript's text item delimiters to startText1
    set endItems to text item -1 of SearchText
    set AppleScript's text item delimiters to endText
    set beginningToEnd to text item 1 of endItems
    set AppleScript's text item delimiters to startText2
    set finalText to (text items 2 thru -1 of beginningToEnd) as text
    set AppleScript's text item delimiters to tid
    return finalText
end extractBetween

尝试：

set xxx to read alias "Mac OS X:Users:paolo:Desktop:paolo.html"
set yyy to do shell script "echo " & quoted form of xxx & " | grep -o \\<table.*table\\>"

行之有效的单线奇迹：

告诉应用程序“Safari”将 sourceCode 设置为字符（in 的偏移量<table（文档 1 的源作为字符串））到（（文档 1 的源作为字符串的“/table”的偏移量））+（“/table”的计数)) of (source of document 1 as string) as string
