Delete all lines that have a specific string

Question

I would like to delete all lines that have the string Excluído, searching from one specific string to the end of another. Example:

<p class="FolderPath">
    <table class="DiffTable">
        <tr>
                <td class="DiffName">
                    <a name="I36676">
                    </a>
                </td>
                <td>
                    Excluído no destino
                </td>
           </tr>
         </table>
</p>

Delete all lines in the middle of the string Excluído starting the search for the string from <p class="FolderPath"> up to the string </p>. I know how to delete the line containing the string:

sed '/Excluído/d' arquivo.txt

What it would be like to erase N lines ? starting from <p class="FolderPath"> up to the string </p>?

Answer 1

I made a quick solution here, then I add a more "polished".

sed -n '/DiffTable/,/<\/p>/p' arquivo.html |grep -q Excluído && sed '/"DiffTable"/,/<\/p>/{//!d}' arquivo.html || echo "Palavra buscada nao existe"

Parameters:

sed -n '/Difftable/,/</p>/p' file.html |grep -q Excluded &&

sed will extract all content between Difftable and </p> and with grep we check if the Deleted string exists.

sed '/"Difftable"/,/</p>/{//! d}' file.html

This is where we replace, excluding all Difftable and </p> lines. The parameter {//!d} Keep the lines of the searched tags, if you want to delete, switch to just d

|| echo "Word sought does not exist"

Just to let you know the word wasn’t found in the grep

Answer 2

Using Perl:

perl -n0E 'say grep !/Excluído/ , split(/(<p class="FolderPath">.*?<\/p>)/s)'

where:

• split(/(<p class="FolderPath">.*?<\/p>)/s) divides the input file by paragraphs and its intermediate
• say grep !/Excluído/ prints the drives that do not contain "Deleted"
• perl -n0E process the whole file at once
