tags

问题 I've got a bunch of XML files, I wish to detect and remove empty tags inside them. like: <My></My> <Your/> <sometags> <his> </his> <hasContent>sdfaf</hasContent> </sometags> They're all kinds of empty tags ( My , Your , his ) I wish to remove.

问题 I have recently started using the PHP shorthand <?= ?> tags to echo variables etc in my PHP scripts. However I find if I want to then comment out the variable, e.g. <?= //$myVariable; ?> i get a syntax error. Is it safe to just do this: <?//= $myVariable; ?> Many Thanks! 回答1: The short tag <?= ... ?> is translated into <?php echo ...; ?> So to comment it out, you have to put something into ... that always shows up as empty. Here's the shortest I can come up with: <?= false && ... ?> This

问题 This is my template code: {{ can_edit|yesno:'Allow edit,View Only' }} But I want to translate it automatically from my translation strings, so I did this: {{ can_edit|yesno:'{% trans "option_allow_edit" %},{% trans "option_allow_edit" %}' }} But it doesn't work, because it escapes the {% trans %} tags.
