Browsing XSLT with Vim by adding a Custom Language to Ctags

XSLT Source Code Browsing with Vim and Ctags

Creating a tags file

1) Test out the regular-expressions for your custom language:

$> egrep 'pattern' *.xsl

2) Copy-paste custom language with the above regular-expressions into ~/.ctags.

$> vi ~/.ctags
--langdef=EXSLT
--langmap=EXSLT:.xsl
--regex-EXSLT=/--regex-EXSLT=/--regex-EXSLT=/$> cd srcdir
$> ctags -R *
