Parsing JSP files and adding a Line


#1

Basically, I’m still pretty much freshmeat when it comes to Ruby, but
I’m intrigued by the language and wanted to start playing around w/ it
for the J2EE project that I’m on.

I wrote some Ruby Code that would find all the jsp’s in our project
(around 200) and look for a XML-Tag and after this tag it would insert a
new line w/ another tag… Some basic scripting. But I doubt I’m doing
it the most efficient way.

Another problem I have is if within the original JSP file, a Tag carries
over onto the next line. I would ideally like to find a Xml-Tag and
insert another block after the end of it. What would be the best way of
doing so? Thanks.

Here’s the relevant code:

def insertStr(fname, str, regexpr, isHeader)
notAdded = true
File.open(fname, ‘r+’) do |f| # open file for update
lines = f.readlines # read into array of lines
lines.each do |line| # modify lines
if notAdded
if line =~ regexpr # If the tag is found
if isHeader # insert include string
line << str + “\n”
else
line.replace(str + “\n” + line)
end
notAdded = false # make sure nothing else can be
inserted
end
end

end
f.pos = 0                         # back to start
f.print lines                     # write out modified lines
f.truncate(f.pos)                 # truncate to new length

end # file is automatically closed
return !notAdded
end

A Xml-Parser might be able to help?
