I used the WikiExtractor to extract the XML dump into JSON files for further pre-processing of the data. My Problem is that the title is always part of the text.

Here is an example:

I'm a javaScript begginer. This function works and allows me to sorting list by ascendant and descendant by clicking in a button but I would like to know if it's properly written or maybe it can be simplified or written differently. Thanks in advance.

index.html

For each element in the file (row), I need to create a new dictionary where the keys are the property names from the header row (Atomic Number, Atomic Name, etc) and the values are the values for each property. However, I cannot create specific dictionary for each element. My output is totally different from the given output. That's an assignment therefore, getting the whole code doesn't make sense. Can you tell me what my mistake is, how I can fix it?

This is my short raw data of the inputted file:

So I've been working on this program for a while and I have gotten it to a point where it compiles just fine but when I run it I get a Segmentation Fault. I've backtraced the fault via gdb to the function below but cannot for the life of me see where the problem is, and I am not versed enough with gdb to determine any more details on the origin of the fault. Like the question says I'm trying to read from a file into a dynamically allocated linked list where each node of the list has a pointer to a struct called Element. Then I need to convert that linked list to an array of pointers to struct Element. I hope that a fresh pair of eyes can see some mistake I've made that I have been blind to.

UPDATE: Added rest of source files. Added gdb backtrace snippet.

Element.h

I have an >> TreeMap that I'm trying to add keys and values to, however I don't know how to add multiple values to keys, I've looked at other posts and searched online but couldn't find anything for my code. I have a list of elements (periodic elements) of which I'm iterating over, the elements contain details of element name, group number, weight etc. and I'm trying to use the group number as the key, and then the use all the other values (weight, name etc.), including the key as they values.

So something like this:
