I'm attempting to extract text from mixed content xml, modify that text, and then replace it back into an xml document at the correct position. The difficulty comes when setting text that contains mixed content...doing so eliminates child tags. 
Example text:

<paragraph> Some <bold>text</bold> here which may be any <bold>length<
+/bold> and <bold>contain</bold> a number of child tags.</paragraph>

Here is the code I am developing. The &choiceReplace sub simply searches through the passed argument string and replaces matched words (which will most always alter the length of the string). 
use XML::Twig;
my $twig = new XML::Twig(TwigHandlers => { 'bold' => \&bold, 'p'  => \
+&paragraph, 'li'  => \&ordered_list},TwigRoots => {body => 1});

sub bold {
    my ($twig, $bold,) = @_;
        my $bold_text = $bold->text;
    &choiceReplace($bold_text,$file);
        $bold->set_text($bold_text);
         }
 

sub paragraph {
    my ($twig, $para,) = @_;
    my $para_text = $para->text;
    &choiceReplace($para_text,$file);
    $bold->set_text($bold_text);
                  }

The child text from the paragraph tag may contain replaced search words. When this is true, the set_text command replaces the <bold> tags with just a text string. I understand why this occurs, but is there a better method of cycling through the <paragraph> children text without affecting the <bold> tags? It seems to me that I need to move through each individual child tag by tag. Is this possible without knowing what tags/text I might encounter? Will the mixed content allow me to alter just the <paragraph> text? And still maintain the <bold> tags?

Any guidance is much appreciated.
