Hi all, I have a really bad feeling about posting this here, but I'm kinda stumped. I've only just discovered the wonder that is ruby and so have started playing around with a number of projects. One of them involves doing a little string parsing (as you'd expect). However, when I try to make use of the StringScanner from the core API, I get the strangest message: NameError: uninitialized constant StringScanner To put it in context: !#/usr/bin/ruby -w s = StringScanner.new("My test string") I know... not exactally rocket science here. I just don't understand why it's not working. Perhaps a corrupt installation? I can't for the life of me figure out what I'm doing wrong... I'm running the latest stable release of ruby (that I know of) ruby 1.8.3 (2005-09-21) [i386-linux] I get the same problem when attempting to test the code with irb. Any thoughts suggestions would be greatly appreciated. Best regards, ~Neowulf

Thanks Dan, I feel like a right idiot. I suspected it'd be something simple The API docs weren't real clear to me about which library to include. Thanks again for the assistance. ~Neowulf

We're pretty nice and almost never bite. ;) Feel free to ask future questions. > However, when I try to make use of the StringScanner from the core > API, I know you've already got an answer, but this is the source of your confusion and I thought I would see if I could clear it up for you. Everything that is "Core Ruby" can be used without a require. Now Ruby also ships with a "Standard Library", which is a collection of useful extra libraries you can also use (but with a require). StringScanner is a Standard Library. You can tell by looking at which link they are documented under, from this page: http://www.ruby-doc.org/ Hope that helps. James Edward G. II

Hi James, Thanks for the additional information. That makes things much clearer. Though I greatly appreciate the help, I'll try to keep the annoying questions to a minimum :) Does the brain good to do some thinking on ones own sometimes :) I'll be sure to call again should I hit another wall. My current exercise is creating a script to scan through my systems log files and autoblock the script kiddies who insist on trying their luck with my SSH server. Seemed like a nice, simple way to try out a few different ideas with Ruby. Might even post it when I'm done and see what you guys think. We'll see how it goes :) Thanks again. ~Neowulf

Hi everybody I've to parse the open office documents and upload it to the database in ruby on rails and in linux platform. I've not found any gem to accomplish that. Now i got a idea of converting the open office documents to XML format and then to parse the XML content to finish up with my task. Is it possible? Is there standard ruby on rails libraries to do this task? Guide me in achieving this... Thanks in advance Anandh

Do you want to store it as blob, in an XML enabled database, as plain text, as...? Btw, it never hurts to include "please" when asking for something. Please help keep this a friendly place.

Thanks for your kind reply. I've to create a open office.org document containing the students details such as name,registernumber etc. Then i've to parse these strings and map these details into the corresponding table in the database. can you please guide me in accomplishing this task. Thanks in advance Anandh

Hey, You can use LibXML-Ruby 1.1.2, Hpricot or REXML for parsing the xml and retrieving the data. http://code.whytheluckystiff.net/doc/hpricot/ -Hpricot http://www.ruby-doc.org/stdlib/libdoc/rexml/rdoc/index.html -REXML http://libxml.rubyforge.org/rdoc/index.html -LibXML From the above links you find the required information.

Isn't OOo's native format ODF, which is an XML format? So why do you need to convert it to XML?

I'm not exactly getting what you are trying to say. Can you please make it clear.

Oracle? sqlite? We have no clue unless you tell us. Also, we don't know what your schema is, so unless you give us more specific information other than "I want to parse open office document and put it into the database", nobody here can help you. Ok, let me make it a bit easier for you. I want you to fill in the following blanks: Hello, I am trying to build an application that does ____________(please put in something other than parsing an office document and put it into a database). The application requires us to commit the contents of a file into a database. The file is in offfice format and contains data as follows ____________(put in sample data here). I need to take this file and stick its contents into a database. We are using _______(mysql,oracle...whichever one you are using). Thank you, Jayanth

Dear Jayanth and others Thank you for your time. In simpler terms, I am looking to implement a functionality where the user of my application would upload a ODT document. My application has to read the ODT document and write the fields in to some database. I guess i need a gem which helps me to read the odt document here, writing it into database is not a problem. On the other hand, If there is no gem to read the ODT file, then i am looking for a gem which can help me convert the ODT file in to xml file. I am comfortable parsing the xml file and go further. Summary: What do i need to know? 1. Is there a gem which helps me to read ODT file? Similarly is there any gem available in linux (platform independent) to read MS doc file. I am expecting my user to upload his document files from any OS and my server to be running in any platform. I guess i am clear. 2. Is there any gem which can convert the ODT files in to xml file? Thank you once again for your kind help. Best Regards Anandh

An OpenOffice document is a package of XML files zipped into a single file. Change the .odt extension to .zip, unzip it, and you'll see.
