I am currently trying to build an iOS game that match word with its definition for myself and my classmates.
I'm having a hard time thinking how do I go about converting a list of words with their definitions in a .docx files into something(JSON, XML, ...) that I can then read it into an Array or Dictionary.
Most of the words in the .docx have the following format:
" Word (): Definition. "
This would be easier with excel. Excel already has the function to export to xml, and should make your life a lot easier, instead of getting all the words out of docx and then converting them to either JSON or XML.

Is there an existing parser to parse json-ld to markdown? I want to generate documentation from my jsonld file. If such a thing doesn't exist, how should I go ahead writing one? or perhaps I could use a json to markdown converter? Any suggestions on how could do this?
I was just googling for such a program, and found your question.
The closest things I could find are: ocxmd, which is an extension to Markdown; and md-ld, which does not even use proper Markdown - instead, it apparently creates an incompatible version of the format which can be parsed to JSON-LD.
If I were writing such a converter in Python, I would use:
pyld to parse JSON-LD files and expand them using the #context;
And a template engine, likely Jinja2, to generate Markdown representation of every node of the JSON-LD document.
The program would be based on recursion. You might have separate functions to display:
URIs,
Numbers,
Images,
...
The program will recurse over the JSON-LD document and convert each of its sections into Markdown format.
I am working with very large JSON files, so I do not want to read the entire file and then iterate and parse each data entry.
Instead, I would like to iterate on the JSON file itself (for example: line-by-line/one object at a time).
I thought about holding the next line location as part of the current line data, so the JSON is a semi linked list, but I did not manage to extract a specific line from the JSON file.
Am I missing an easier way to achieve that? Is it even possible to extract and parse a specific line from a JSON file?
Thanks a lot!
JSON is not a line oriented format, so the idea of parsing "line by line" doesn't really make sense.
That said, there is at least one event-driven JSON parser for iOS that I know of, https://github.com/stig/json-framework. The built-in parser NSJSONSerialization only works on entire files.
I know how to convert a Set of text or web page files in to arff file using TextDirectoryLoader.
I want to know how to convert a single Text file in to Arff file.
Any help will be highly appreciated.
Please be more specific. Anyway:
If the text in the file corresponds to a single document (that it, a
single instance), then all you need is to replace all "new lines"
with the escape code \n to make the full text be in a single line,
then manually format as an arff with a single text attribute and a
single instance.
If the text corresponds to several instances (e.g. documents), then I
suggest to make an script to break it into several files and to apply
TextDirectoryLoader. If there is any specific formating (e.g.
instances are enclosed in XML tags), you can either do the same (by
taking advantage of the XML format), or to write a custom Loader
class in WEKA to recognize your format and build an Instances object.
If you post an example, it would be easier to get a more precise suggestion.
I've unicode character text for indian language(telugu) like this
పురాణాలు
I'm getting the above text from database to an xml file format. I'm reading the xml file and
when i am printing the text it is showing as పురాణాలు
Is there any way print the text as it is without any encoded character type &#...?
How are you parsing the XML? A proper XML parser should decode the numeric references.
I'm guessing that you are attempting to hand parse an XML document instead of relying on NSXMLParser. If so, you really should use an XML parser. Bad Guess on my part, it's likely that the entities are being double encoded.
To answer your question directly, Objective C HTML escape/unescape shows how to decode entities with a quick and dirty method.
I'm trying to figure out how to read in the contents of an XLS document and I'm able to get the bytes just fine, but I don't have any clue where to go from here. Trying [[NSString alloc] initWithBytes:data.bytes length:data.length encoding:NSUTF8StringEncoding] and [NSString stringWithUTF8String:data.bytes] both don't get me anywhere (null). What are you supposed to do to read in the contents of an XLS file?
Trying to combine two answer.
"There is no innate ability to read Excel data into a Foundation container, like an NSArray or NSDictionary. You could, however, convert the file (with Excel) to a comma-separated-value (CSV) file and then parse each line's cells on the iPhone using the NSString instance method -componentsSeparatedByString:."
"A comma-separated values (CSV) file stores tabular data (numbers and text) in plain-text form. Plain text means that the file is a sequence of characters, with no data that has to be interpreted instead, as binary numbers. A CSV file consists of any number of records, separated by line breaks of some kind; each record consists of fields, separated by some other character or string, most commonly a literal TAB or comma. Usually, all records have an identical sequence of fields"

Even though saving your Excel file to CSV is the easier answer, sometimes that's not really what you're looking for, so I created QZXLSReader. It's a drag-and-drop solution so it's a lot easier to use. I don't think it's as feature complete, but it worked for me.
It's basically a library that can open XLS files and parse them into Obj-C classes. Once you have the classes, it's very easy to send them to Core Data or a dictionary or what have you.
I hope it helps!
