在 Notepad++ 中替换为正则表达式

Question

I'm trying to replace the part the text with the same text and some extra, example:

Initial text

<href="../doc/d5807346.pdf" class="document">3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE</a></div><div style="clear:both;"></div>

After

<href="../doc/d5807346.pdf" class="document" download="3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE">3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE</a></div><div style="clear:both;"></div>

I'm using in Notepad++ the following Regex:

• Find: ((?<=class="document">).*?(?=<))
• Replace with: download="\1">\1

End result is not what I'm expecting, note the > between class="document" and download:

<href="../doc/d5807346.pdf" class="document"> download="3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE">3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE</a></div><div style="clear:both;"></div>

I'm stuck on trying to figure out how to prevent that.

Answer 1

Try this:

1. Find: (?:class="document">)([^<]*)
2. Replace (corrected): class="document">download="$1">$1

Tested in N++

Before: <href="../doc/d5807346.pdf" class="document">3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE</a></div><div style="clear:both;"></div>

After: <href="../doc/d5807346.pdf" class="document">download="3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE">3.2.1.&nbsp;&nbsp;&nbsp;&nbsp;EXAMPLE</a></div><div style="clear:both;"></div>

Answer 2

• Ctrl + H
• Find what: (class="document")>([^<]+)
• Replace with: $1 download="$2">$2
• CHECK Wrap around
• CHECK Regular expression
• Replace all

Explanation:

(class="document")      # group 1
>                       # literally >
([^<]+)                 # group 2, 1 or more any character that is not "<"

Replacement:

$1              # content of group 1 + a space
download="      # literally
$2              # content of group 2
">              # literally
$2              # content f group 2
