Select whole HTML / XML tag

Select whole HTML / XML tag

…

How this looks:

Some tips:

– This is version 0.01 but works good for me.

– The purpose is to select an whole …

– 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 = ““;

Examples:
= OK
= OK
= OK
/> = OK
< tag > = wrong
= wrong

– put your cursor ON the word of the opening tag or at one side:

Examples:
<|tag yxz> = OK
= OK
= OK
= OK
= 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.
