I have an XML file that looks like:    &lt;results&gt;     &lt;result&gt;       &lt;title&gt;Welcome+to+The+JASON+Project%21&lt;/title&gt;       &lt;url&gt;http%3A%2F%2Fwww.jason.org%2F&lt;/url&gt;       &lt;domain /&gt;       &lt;inside_links&gt;         &lt;inside_link&gt;           &lt;description&gt;News&lt;/description&gt;           &lt;url&gt;http%3A%2F%2Fwww.jason.org%2FPublic%2FNews%2FNews.aspx&lt;/url&gt;         &lt;/inside_link&gt;         &lt;inside_link&gt;           &lt;description&gt;register&lt;/description&gt;           &lt;url&gt;http%3A%2F%2Fwww.jason.org%2Fpublic%2Fregistration%2Fregistration.aspx&lt;/url&gt;         &lt;/inside_link&gt;         &lt;inside_link&gt;           &lt;description&gt;Argonauts&lt;/description&gt;           &lt;url&gt;http%3A%2F%2Fwww.jason.org%2FPublic%2FArgonauts%2FArgonauts.aspx&lt;/url&gt;         &lt;/inside_link&gt;         &lt;inside_link&gt;           &lt;description&gt;Curriculum&lt;/description&gt;           &lt;url&gt;http%3A%2F%2Fwww.jason.org%2FPublic%2FCurriculum%2FCurriculum.aspx&lt;/url&gt;         &lt;/inside_link&gt;         &lt;inside_link&gt;           &lt;description&gt;Credits&lt;/description&gt;           &lt;url&gt;http%3A%2F%2Fwww.jason.org%2Fpublic%2FMisc%2FCredits.aspx&lt;/url&gt;         &lt;/inside_link&gt;       &lt;/inside_links&gt;       &lt;inside_keywords&gt;National+Science+Education+Standards, National+Geographic+Society, Physical+Science, Professional+Development, Earth+Science&lt;/inside_keywords&gt;     &lt;/result&gt;   &lt;/results&gt;   ...And I'm very confused as to how to read it. I simply want to get the Title, Description, and URL into separate strings.

Can somebody please help me out with this?

What Is Energy? Where did it come from? The simplistic undergrad explanation aside, I've never really understood what energy really is. I've been told that it's something when converted from one kind of something to another kind, or does some "work", as defined by us, but what is that something?  Moreover, if the total amount of energy in the universe is finite and we cannot create energy. Then, where did it come from? I've learned from thermodynamics where it goes, but where does it come from?  I know this sounds like something trivially simple, but there is so much going on in the physical universe and I just can't grasp what it is. Maybe it is because I lack the mathematical understanding that I can't grasp the subtle things the universe is doing. Still, I want to understand what it is doing.  How do I get to the point of understanding what it's doing?  (Note: What prompted me to ask this was . I'm afraid that it just puzzled me further and I sat there staring at the screen for a good 10 minutes.) I need two bib-like sections: a "References" giving works explicitly cited in my text, and a "Bibliography" (or "Further reading" if you prefer) giving everything from my bibfile that didn't already appear in "References". The first is of course completely standard, but the second... I'm stumped.  Further loose constraints: I'm somewhat committed to biblatex and the biblatex-apa style. But I'll happily accept an answer not related to them if there's any chance I can adapt it. Why not to extend the set of natural numbers to make it closed under division by zero? I was trying to fit my data into various models and figured out that the fitdistr function from library MASS of R gives me Negative Binomial as the best-fit. Now from the  page, the definition is given as:     NegBin(r,p) distribution describes the probability of k failures and r   successes in k+r Bernoulli(p) trials   with success on the last trial.   Using R to perform model fitting gives me two parameters mean and dispersion parameter. I am not understanding how to interpret these because I cannot see these parameters on the wiki page. All I can see is the following formula:    where k is the number of observations and r=0...n. Now how do I relate these with the parameters given by R? The help file does not provide much information either.   Also, just to say a few words about my experiment: In a social experiment that I was conducting, I was trying to count the number of people each user contacted in a period of 10 days. The population size was 100 for the experiment.   Now, if the model fits the Negative Binomial, I can blindly say that it follows that distribution but I really want to understand the intuitive meaning behind this. What does it mean to say that the number of people contacted by my test subjects follows a negative binomial distribution? Can someone please help clarify this? jQuery Datepicker with text input that doesn't allow user input Get Edge / Vertex / Face from mouse position Inner product of two continuous maps is continuous Let f,g be continuous maps of S in $\mathbb{R}^n$, to $\mathbb{R}^m$. Show the inner product h(x) = $\langle f(x), g(x)\rangle$ is continuous.  My attempt: Since f,g are continuous, their product is a continuous mapping, so for $\epsilon \gt 0\: t.e\:  \delta \gt 0$ such that $\parallel x - a\parallel \lt \delta $ implies $\parallel \langle f(x),g(x)\rangle - \langle f(a)g(a)\rangle \parallel \le\parallel f(x)g(x) - f(a)g(a)\parallel \lt \epsilon$ by schwartz inequality. I initially thought that dark energy must in some way violate conservation of mass and energy since the component of the energy density of space that comes from dark energy is constant, and space is expanding. Therefore, as space expands the energy in the universe that comes from dark energy would increase. I presumed the source of this energy was not coming from the conversion of other types of energy to dark energy, so it must violate conservation.  I decided to Google this and came upon this article:    It says that dark energy does NOT violate conservation and quotes Carroll, Press, and Turner (1992):  "…the patch does negative work on its surroundings, because it has negative pressure. Assuming the patch expands adiabatically [i.e. without loss or gain of heat], one may equate this negative work to the increase of mass/energy of the patch. One thereby recovers the correct equation of state for dark energy: P = – ρ c2. So the mathematics is consistent."  Is there a way to explain this in layman's terms? (The blog attempted to do this, but it was very unclear to me.) More specifically, can you explain where my initial train of thought described above fails when I erroneously concluded that dark energy violates conservation?  Thank you.

Group of even order contains an element of order 2 I am working on the following problem from group theory:     If $G$ is a group of order $2n$, show that the number of elements of $G$ of order $2$ is odd.   That is, for some integer $k$, there are $2k+1$ elements $a$ such that $a \in G,\;\; a*a = e$, where $e$ is the identity element of $G$. You can reach this IP address  (if my computer is online). I want to assign a domain to it so I wonder how is that possible when I have no DNS? I do own my domain which is ".com". My IP is static.  Thanks Can a Paladin take levels of other classes? In 3.5 D&amp;D,  have severe restrictions on multiclassing:     Like a member of any other class, a paladin may be a multiclass character, but multiclass paladins face a special restriction. A paladin who gains a level in any class other than paladin may never again raise her paladin level, though she retains all her paladin abilities.   Because Pathfinder is based on 3.5 D&amp;D, do Pathfinder paladins face the same restriction? That is, if a Paladin multiclasses to say, a fighter, can she take another level of Paladin later on?

When you are viewing an app in Google Play store, it displays the following : Updated, Size, Installs, Current Version, Requires Android, and Rating.

I'm not quite sure if stackoverflow or serverfault is the forum to use for this question, but ill try here.  Is there some command I can use or a file I can check in order to find out which process scheduler I'm using on my Linux system? I am not looking for the I/O scheduler, but the process scheduler, and please, do not refer to guides or howtos for what a scheduler is, what I'm simply asking is if there is a command or file I can run/check to see this. I could check the doc for my kernel but again I'm just wondering if there is a command or file i can check.  I might have been a little redundant above but that's because the posts I've seen people seem to confuse process scheduler with the i/o scheduler, and they don't seem to answer the actual question, just provide links to what a scheduler is which is not what I'm after here, so apologies if the above comments sounded rude.
