我想在以下示例中添加 html 链接:

  1. Blah Blah Blah BZ#01234 Blah Blah Blah
  2. Blah Blah Blah BZ#0124 Blah Blah Blah
  3. Blah Blah Blah BZ 012345 Blah Blah Blah
  4. Blah Complex Blah BZ#123 , 345, 567,2341 Blah

所以看起来像:

  1. 胡说八道 <a href="http://bz.com/show_bug.cgi?id=01234">BZ#01234</a> 胡说八道
  2. 废话废话 <a href="http://bz.com/show_bug.cgi?id=0124">BZ#0124</a> 废话废话
  3. Blah Blah Blah <a href="http://bz.com/show_bug.cgi?id=012345">BZ 012345</a> Blah Blah Blah
  4. 废话复杂废话 <a href="http://bz.com/show_bug.cgi?id=123">BZ#123</a> , <a href="http://bz.com/show_bug.cgi? id=345">345</a>、<a href="http://bz.com/show_bug.cgi?id=567">567</a>、<a href="http://bz. com/show_bug.cgi?id=2341">2341</a> 废话

所以我想这是一个查找匹配项的正则表达式工作,以及添加 html 链接的一些 PowerShell 魔法。我认为正则表达式((BZ#)|(BZ ))[0-9]+可以匹配除复杂示例之外的所有内容,但我不太了解正则表达式,无法确定,或者如何在 PowerShell 中对其进行测试。

我认为这可行,这取决于输入的可变性。

$inputstring = @'
Blah Blah Blah BZ#01234 Blah Blah Blah
Blah Blah Blah BZ#0124 Blah Blah Blah
Blah Blah Blah BZ 012345 Blah Blah Blah
Blah Complex Blah BZ#123 , 345, 567,2341 Blah
'@

# Split the input into an array of strings
$lines = $inputstring -split '[\r\n]'

# Setup patterns to match against
$pattern1 = "(.*)\sBZ#(\d+) , (\d+), (\d+),(\d+) (.*)"
$pattern2 = "(.*)\sBZ#(\d+)\s(.*)"
$pattern3 = "(.*)\sBZ (\d+)\s(.*)"

# Loop through each line
for($i = 0; $i -lt $lines.count; $i++)
{
    # Start off assuming the current line produces no output
    $output = ""

    # Look for volumes with drive letters
    if($lines[$i] -match $pattern1)
    {
        $output = $matches[1] + " <a href=`"http://bz.com/show_bug.cgi?id=" + $matches[2] + "`">BZ#" + $matches[2] + "</a> , " + 
            "<a href=`"http://bz.com/show_bug.cgi?id=" + $matches[3] + "`">" + $matches[3] + "</a>, " + 
            "<a href=`"http://bz.com/show_bug.cgi?id=" + $matches[4] + "`">" + $matches[4] + "</a>," + 
            "<a href=`"http://bz.com/show_bug.cgi?id=" + $matches[5] + "`">" + $matches[5] + "</a> " + 
            $matches[6]
    }
    elseif($lines[$i] -match $pattern2)
    {
        $output = $matches[1] + " <a href=`"http://bz.com/show_bug.cgi?id=" + $matches[2] + "`">BZ#" + $matches[2] + "</a> " + $matches[3]
    }
    elseif($lines[$i] -match $pattern3)
    {
        $output = $matches[1] + " <a href=`"http://bz.com/show_bug.cgi?id=" + $matches[2] + "`">BZ " + $matches[2] + "</a> " + $matches[3]
    }

    # Write out any output that was produced
    if($output -ne "")
    {
        $output
    }
}

输出:

Blah Blah Blah <a href="http://bz.com/show_bug.cgi?id=01234">BZ#01234</a> Blah Blah Blah
Blah Blah Blah <a href="http://bz.com/show_bug.cgi?id=0124">BZ#0124</a> Blah Blah Blah
Blah Blah Blah <a href="http://bz.com/show_bug.cgi?id=012345">BZ 012345</a> Blah Blah Blah
Blah Complex Blah <a href="http://bz.com/show_bug.cgi?id=123">BZ#123</a> , <a href="http://bz.com/show_bug.cgi?id=345">345</a>, <a href="http://bz.com/show_bug.cgi?id=567">567</a>,<a href="http://bz.com/show_bug.cgi?id=2341">2341</a> Blah
