正则表达式删除标签Notepad ++中的特定文本

Question

Hello i'm a bit new to coding and trying to understand how regular expressions works,

so i'm working on an XML file with products and want to delete specific text inside a tag. From the example below:

 <descr>&lt;br/&gt; &lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt; &lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;br/&gt;</descr> 

i want to remove this part:

 <P> </P> 

cause its interfering with the text format. This may happen multiple times within the tag, so i want to remove it every time. Can i do this with a regex in Notepad++ ?

Answer 1

I was able to do your replace with this regex:

(<descr>[\s\S]*?)&lt;P&gt;&amp;nbsp;&lt;\/P&gt;([\s\S]*?<\/descr>)

Replacing it by:

$1 SUCCESS $2

I used as input:

<descr>&lt;br/&gt;
&lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;br/&gt;</descr>

<other>&lt;br/&gt;
&lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;br/&gt;</other>

<descr>&lt;br/&gt;
&lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;br/&gt;</descr>

And it became:

<descr>&lt;br/&gt;
&lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt;
 SUCCESS &lt;br/&gt;</descr>

<other>&lt;br/&gt;
&lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;br/&gt;</other>

<descr>&lt;br/&gt;
&lt;P&gt;SOME RANDOM TEXT&lt;/P&gt;&lt;br/&gt;
 SUCCESS &lt;br/&gt;</descr>

Explaining the regex:

(                                 # start of group 1
    <descr>                           # match the open tag
    [\s\S]                            # space or non-space characters = anything
          *?                          # the minimum amount till the next match
)                                 # end of group 1
&lt;P&gt;&amp;nbsp;&lt;\/P&gt;    # your pattern, please note I had to escape the slash
(                                 # start of group 2
    [\s\S]                            # space or non-space characters = anything
          *?                          # the minimum amount till the next match
    <\/descr>                         # the closing tag, again look the escaped slash
)                                 # end of group 2

And the replace:

$1 SUCCESS $2                     # $1 stores the value matched by the group 1
                                  # $2 stores the value matched by the group 2
                                  # The text " SUCCESS " was an example, it could be empty
