in thread substitution in textual area of HTML file

If my text has some formatting tags (<bold> for example), the formatted text is stripped off.

my $html = '<ul><div class="txt" style="position:absolute; left:84px; +top:73px;"><span id="f1" style="font-size:11px;vertical-align:baselin +e;color:rgba(0,0,0,1);">technology of S2S translation, <b>also</b> kn +own as Spoken Language Translation (SLT),</span></div><div class="txt +" style="position:absolute; left:44px; top:73px;"><span id="f1" style +="font-size:11px;vertical-align:baseline;color:rgba(0,0,0,1);">is a n +ew application of AI,</span></div><li>there</li><li>everyone</li></ul +> ';

Becoming:

<ul><div class="txt" style="position:absolute; left:84px; top:73px;">t +echnology of S2S translation, known as Derp! Language Translation (S +LT),</div><div class="txt" style="position:absolute; left:44px; top:7 +3px;"><span id="f1" style="font-size:11px;vertical-align:baseline;col +or:rgba(0,0,0,1);">is a new application of AI,</span></div><li>there< +/li><li>everyone</li></ul>

I am starting to realize that my task is more difficult than I thought at first... but working on

    This doesn't seem to be the case:

    #!/usr/bin/perl use strict; use warnings; use feature 'say'; use Mojo::DOM; my $html = '<ul><div class="txt" style="position:absolute; left:84px; +top:73px;"><span id="f1" style="font-size:11px;vertical-align:baselin +e;color:rgba(0,0,0,1);">technology of S2S translation, <b>also</b> kn +own as <b>Spoken</b> Language Translation (SLT),</span></div><div cla +ss="txt" style="position:absolute; left:44px; top:73px;"><span id="f1 +" style="font-size:11px;vertical-align:baseline;color:rgba(0,0,0,1);" +>is a new application of AI,</span></div><li>there</li><li>everyone</ +li></ul> '; my $dom = Mojo::DOM->new( $html ); $dom->find('span')->each( sub { $_->content( $_->content =~ s/Spoken/D +erp/r ) } ); say $dom->content;

    Output:

    <ul><div class="txt" style="position:absolute; left:84px; top:73px;">< +span id="f1" style="font-size:11px;vertical-align:baseline;color:rgba +(0,0,0,1);">technology of S2S translation, <b>also</b> known as <b>De +rp</b> Language Translation (SLT),</span></div><div class="txt" style +="position:absolute; left:44px; top:73px;"><span id="f1" style="font- +size:11px;vertical-align:baseline;color:rgba(0,0,0,1);">is a new appl +ication of AI,</span></div><li>there</li><li>everyone</li></ul>

    The <b></b> tags around 'also' are still there, and replacing 'Spoken' with 'Derp' also maintains the associated <b></b> tags. Perhaps you've altered some code?

      I was using your first code which has $id->text instead of $id->content. Using "content" made the trick.

      I am using the first script because of the nice loop. My final goal is to wrap the matching string(s) between tags (a simple replacement of match with tag+match+tag should do it). The hard part is that I need to match n-grams that possibly are split between two nodes (end of 1st node and begin of next one), with the loop I may find some working solution (my idea is to scan a window of two nodes at a time). Why this? Because I am parsing the output of pdftohtml which splits natural language sentences into lines, each line wrapped in its own tags. In the example above, it could be that I need to match the 2-gram "Translation is", which is in 2 adjacent DOMs. This is quite challenging (at least for my 0-parsing-abilities), but you have brought me near my goal. So time to play now.

      Edit

      Just for the sake of experimenting/learning, I tried with these two HTML snippets:

      my $html = '<ul><div class="txt" style="position:absolute; left:84px; +top:73px;"><span id="f1" style="font-size:11px;vertical-align:baselin +e;color:rgba(0,0,0,1);">technology of S2S translation, <b>also</b> kn +own as Spoken Language Translation (SLT),</span></div><div class="txt +" style="position:absolute; left:44px; top:73px;"><span id="f1" style +="font-size:11px;vertical-align:baseline;color:rgba(0,0,0,1);">is a n +ew application of AI,</span></div><li>there</li><li>everyone</li></ul +> '; my $html = '<ul><div class="txt" style="position:absolute; left:84px; +top:73px;"><span id="f1" style="font-size:11px;vertical-align:baselin +e;color:rgba(0,0,0,1);">technology of S2S translation, <b>also</b> kn +own as <p>Spoken</p> Language Translation (SLT),</span></div><div cla +ss="txt" style="position:absolute; left:44px; top:73px;"><span id="f1 +" style="font-size:11px;vertical-align:baseline;color:rgba(0,0,0,1);" +>is a new application of AI,</span></div><li>there</li><li>everyone</ +li></ul> ';

      With the first HTML, using your first script with $id->text, <b>also</b> is not shown, with the second yes. I do not see any rational behind it...

        So ->text will just give you the text, which isn't the same thing as all of the string of HTML within the 'span' tag. ->content is quite different.

    Post a few edge cases of the data you're working with and I'll take a look later on.
