I have a large list of RSS feeds seperated by line breaks, and I want to import them into my rss reader. How would I go about this, and is an OPML file easier than something else? Thank you.
Tried going on some website and converting it, did not work at all.

For a project I'm working on I have a CSV reader to read user input. But that's quite an annoying UX, cause the user has the data in a google sheet/ execl (xlsx) format or numbers format. So if the user did not convert the file to CSV before uploading, they need to navigate to the Numbers app and export the file to file to CSV there.
So I was thinking how can I make this better, first thought, yeah just read the xlsx or numbers file ..... One day googling and trying some stuff, I still didn't find a good approach.
I would love to hear your input, I'm sure somebody out there has experience with this.
I'm thinking about creating an API for it. But I prefer to handle it natively in swift.
Thanks!
I have a requirement to read a pdf file having tabular format data only like in excel file. I need to extract the cell value of given pdf file.
Is it be anyhow possible using itext API. If you have something to share then please share it or any other solutions?
The PDF format is just a canvas where text and graphics are placed without any structure information. As such there aren't any iText-objects in a PDF file. In each page there will probably be a number of Strings, but you can't reconstruct a phrase or a paragraph using these strings. There are probably a number of lines drawn, but you can't retrieve a Table-object based on these lines.
In short: parsing the content of a PDF-file is NOT POSSIBLE with iText.
You can try this! This lets you read PDF pages.
I recently ran into this problem. I wasn't able to make it work with itext.
An alternate solution I found was to open a PDF document in Adobe and export it to xml. At least with my PDF's it preserved the table information and then I was able to programmatically work with the XML to generate tabular files like excel etc.
The other issue I ran into was that Adobe only lets you export one file at a time and I had lots of files. Luckily Adobe also has a merge function. I ended up merging all the files together and then exporting them as one big XML file and working with that file to generate what I needed.
I want to parse an excel sheet and have to display the content in table view. Suggestions please.
The easiest way is to save your excel file as a text file with tab delimiters. This way its straight forward. In case you like to do some "intelligent" parsing - you may just take a look at one of these many parser tutorials for the iPhone. I am sure, you will be able to build on these sample quite easily.
I have an rss reader app which works perfectly on some feeds, but on others it just displays text and no images.
Is it the feed which should be adjusted to publish images or Im sure it is something with the way I read the stream.
Why does it work for some streams(shows entire posts, images, videos etc. from e.g. blogspot rss feeds) but not for other rss feeds?
I have read that the stream itself can be set to publish different content amounts.
How can I parse the feed so that all feeds will work correctly?
It's very likely that it's due to the feed themselves... and not to the reader app.
Feed publisher can decide whether they want to include all or parts only of their content in their feeds (RSS or Atom).
Then, even if they publish all the content, they may decide to publish it as raw text (just the text content) or full XHTML, which would allow the inclusion of images.
Unfortunately, there is little that you can do, except maybe ask the developer of your app to allow to show the original site/page and not just the feed entries.
Ok, so what are the differences between the feeds that work and the feeds that don't? What assumptions do you make about the RSS content, and in what situations are those assumptions not satisfied? When you run the code in the debugger, what do you see when you encounter a feed where images don't work? Also, what code? ;)
I am using ROME library for parsing feeds. I want to know how can I identify a link as an XML link or a normal link. Is there a support for this in ROME.
It sounds like you are saying that you will be getting a bunch of links from somewhere (RSS feed content or something). Then you want to go through them and determine if they are RSS/Atom feeds or if they are regular HTML pages.
You could probably attempt to fetch it with Rome and then see if it throws an exception. A better option might be to pull in the document at the end of each link and see what the header says it is.
Keep in mind that retrieving each link is may run into a problem if someone links to a very large file.
You might look at using the HEAD command to find out what type of file you are going to get at the end of a link before downloading the entire thing.
