Select whole HTML / XML tag
<tag> ... </tag>How this looks:
Some tips:- This is version 0.01 but works good for me.
- The purpose is to select an whole <tag>...</tag>
- Therefore the script takes the word under the cursor (the TAG, i hope)
- then it looks at each line till EOF for the closing tag with same name.
- On the way it counts other opening and closing tag's.
- only if (opening - closing == 0) i assume the right closing tag is found.
That way i can find nested tag's also.
- it works only for proper written tags without spaces due to:
//Set the search pattern:
OpenTag = "<" + TagName;
CloseTag = "</" + TagName + ">";
Examples:
<tag yxz> = OK
<tag> = OK
</tag> = OK
/> = OK
< tag > = wrong
</ tag> = wrong
- put your cursor ON the word of the opening tag or at one side:
Examples:
<|tag yxz> = OK
<t|ag yxz> = OK
<ta|g yxz> = OK
<tag| yxz> = OK
<tag |yxz> = wrong
(but i think that can be improved,
as the whole macro could be more clever)
The macro- save this script as "SelectWholeTag.jsee"
- assign an shortcut to it like "Ctrl+Alt+T"
- or put it as macro into the snippet plugin.
