What's the best library to use to generate RSS for a webserver written in Common Lisp?
Most anything will probably do. Personally, I've been using xml-emitter for my blog's Atom feed, which has worked out well so far.
Just choose whichever XML generation library you like and hack away, I'd say. As others have remarked, RSS is simple; it's little work to generate it manually.
That said, I recommend not generating plain strings directly. Having to deal with quoting data is more of a hassle than installing an XML library, and it's also insecure in case your feed contains data submitted by visitors of your website.
xml-emitter says it has an RSS 2.0 emitter built in.
CL-WHO can generate XML pretty easily.
I am not aware of any specific RSS library. But the format is fairly simple so any library that can write xml will do at that level.
You could have e.g. a look at the nuclblog (http://cyrusharmon.org/projects?project=nuclblog) project as that has the capability to generate an RSS feed for the blog entries it maintains.
cl-rss-gen is a tiny library (LGPL, depends on CL-WHO) that does some boilerplate work for you (supports generating RSS entries directly from CLOS class instances by specifying which slot maps to which attribute).
Take a look at the code before using it, it may give you the idea how it's working and whether you need it or not (as other posters said, you can generate RSS yourself with CL-WHO or any XML generation library).
Oh, and sorry for resurrecting a four years old thread, but if anyone searches for similar library, he/she will find the answer here.

We have a couple of relatively simple websites running on Adobe CQ 5.5 that were developed by a third party. I'm pretty familiar with how CQ works, but I'm working with somebody else's code here and I need to be able to search through all components in the system for a particular string.
The issue is that I can't seem to find a way to search across all of the various .jsp files stored with the various system components. I would have figured that the query tool in CRXDE Lite would have done the trick with something like this:
/jcr:root//*[jcr:contains(., 'Find this exact string in a JSP')] order by #jcr:score
But I've had no luck.
What I am looking for is some sort of global search that includes JSP files. Is that possible? Were I using a regular Java system, any IDE worth the download would be able to do this.
Thanks.
Might not be easiest way, but you can use the VLT tool to checkout the repository into your filesystem. Then you can lookup using whatever tool you prefer. It might even be faster in the long run
I don't have the actual answer but I suppose the JSPs are indexed via a filter that strips out some of their content.
It should be possible to configure the repository to index them as is instead, based on the info at http://wiki.apache.org/jackrabbit/IndexingConfiguration and http://jackrabbit.apache.org/jackrabbit-text-extractors.html
Sorry about the vagueness of this answer - I know the basic principles but to provide the details I would need more time than I can afford now ;-)
I want to extract data from various kinds of blogs and was going through various ways to do it:
API which needs user authentication
XML RPC(Don't know which all support it)
RSS(Again, not sure which blogs support it and even if they do, how much can one get from RSS feeds.)
Atom
I know that this isn't a strictly programming related question but I went forward in asking this as there is heck lot of confusion as to what to use and which is better served?
It would be nice to not use API with Authentication as you not only will have to tackle with varied implementations of Authentication, you also have to deal with varied API limits.
RSS is the oldest that came into use. There are limitations to it. Atom was designed to be the replacement for it, overcoming the limitations of RSS. Atom is just a specialised form of XML RPC. In other words, there are other uses for XML RPC, and Atom is the variation of it you want. All of the above are a type of API. So ideally what you want to do is support RSS and Atom. Sadly Atom and RSS are not backwards compatible. To quote the Wikipedia on "Atom":
In particular, many blog and wiki sites offer their web feeds in the
Atom format.
#porneL's solution is not recommended (at the moment). However in the future, HTML markup is set to change to improve the semantic meaning given to blocks, such as the new <article> tag. This will be yet another way to parse documents. It will be the most versatile, but in my opinion it will be a very long time before it becomes reliable, since many if not most sites suffer from 'tag soup' syndrome.
The most universal "standard" is crawling and parsing HTML.
wget -m http://example.com/
How exactly you do it depends on what are you trying to accomplish and how universal you want to be.
You could use heuristics, similar to what Readability uses, to find articles on a site. You could detect and special-case popular blogging platforms.
Alfresco allows uploading newer versions of documents in the repository and also keeps track of the version history, it seems. However, I could not find any way to compare or diff a document with its prior versions.
Is this possible? are there any good external plugins or tools for this?
I assume you think of something similiar to the good old Unix diff tool which basically compares text files and can show the result in a human readable form.
The general equivalent situation in alfresco is far more complicated. You have an arbitrary amount of properties of different type. The text file you might think of just happens to have character bytes in cm:content.
So to answer your question : I don't know of any extension providing a general diff between versions, but it should not be two hard rolling your own for text files other simple special comparisons. In the former case you might want to have a look at Java library for free-text diff for libraries providing the base functionality.
Looking for the same functionality and found this Alfresco addon

Is it possible to programmatically generate an info path 2007 form template (xsn file=form definition) ?
I know that there is no object model for the infopath 2007 form designer, but does anyone know of any third party libraries?
The form view itself is a xsl file so it should be possible. I would have thought that its a common use case also.
It is possible to generate the manifest.xsf, xsl and xml files from a structured source (let's say an xml) and then pack this (as .cab) with the extension .xsn
(The .xsn file is nothing but a renemed .cab!)
This is only a raw concept - it could be refined if the purpose was a bit more explicit. Why generate? Are you going to create a bunch of different files? What for?
There are no libraries or API's to do this. While generating a template is possible you will need to write it all yourself. Obviously this will not be an easy task and will be prone to errors. I would recommend reviewing your requirements to ensure this is truly necessary. InfoPath is quite flexible, without knowing the details of your project, there is a good chance you can get the functionality you need with a single template.
I thought this was asked before, but 15 minutes of searching on Google and the site search didn't turn anything up...so:
Where can I obtain free (as in beer and/or as in speech) dictionary files? I'm mainly interested in English, but if you know of any dictionary files, please point them out.
Note: This question doesn't have a right/wrong answer, so I made it community-wiki. However, I feel that it might be valuable to not only myself, but anyone who wishes to implement or use a spell checker with various dictionary files.
I have found a SourceForge project called Word List, which appears to have a number of dictionaries. I have downloaded a couple and am currently checking them out.
On Linux you can look in places like /usr/share/dict/words
I would presume that OpenOffice contains dictionaries for several languages.
I don't know what your target platform is but here is a solution that is for VB.NET. It uses the Office libraries which Office in itself isn't free but if your users are all internal and have Office then you could leverage these libs. There is a zip file with the example source code you can download as well.
Check spelling and grammar
There is what appears to be a half-decent dictionary available for free here on CodeProject.com (registration required unfortunately).
