305,976 | 305,977 | jQuery search/replace all body text problems | <p>I am doing a complex language translation in <a href="http://en.wikipedia.org/wiki/JQuery" rel="nofollow">jQuery</a>. I am copying some of the methods used in the jQuery/Google translate, but using our own XML files for getting original English and translated languages.</p>
<p>I am able to easily read English and other language into an array.</p>
<p>But my problem is that some of these text phrases, that we are paying someone to have translated, are going to be inside other sentences inside many different pages.</p>
<p>I have been blasting away, trying different approaches, and still no real luck in finding a useable solution.</p>
<p>In past efforts, I have used the $('body').nodesContainingText() from jQuery-translate, to parse through each text node, then search for that text inside the English array, grab that position, and use that to get the translated version in the other language array.</p>
<p>And that works fine where there are separate text nodes, but still not even close to consistently working on partial replacing.</p>
<p>Seems the more I try to fix the problem, the less it works.</p>
<p>So what I'd really like is some guidance about what I am doing wrong?</p>

1,175,853 | 1,175,854 | Checked exceptions and File.exists() in Java | <p>I have primarily a C# background (and am very much a newbie) so forgive me if my assumptions based on this are the problem.</p>
<p>Simply put, one of the features in a piece of software I'm working on (in Java) has the user input a file name. What I intend to do is have the program loop and append a string to the end of the file name from an array of possible append strings, to see if a file exists, and if it does, open it. I am guaranteed to have only ONE file of a given name, so breaking out of the loop on the first success isn't a bug (if the file name the user specifies is "foo" and the appendStrings array has "bar" and "baz" inside of it, I am guaranteed there will never be both a "foobar" and "foobaz" in the directory). What I eventually came up with was similar to this:</p>
<pre><code>public FileReader LocateFile(String fileName)
{
FileReader toReturn = null;
for(int i = 0; i < appendStrings.length; i++)
{
File locatedFile = new File(fileName + appendStrings[i]);
try
{
toReturn = new FileReader(locatedFile);
}
catch(FileNotFoundException ex)
{
continue;
}
}
//...handling in case I didn't find a file.
}
</code></pre>
<p>Great, it works just fine. Except for two problems:</p>
<ol>
<li>The compiler is upset with me that I'm declaring a variable (ex) that I'm not using. I suppose I could log the exception or something, but that seems ridiculous because this will happen often and I'd rather not fill my log file with excessive noise just to make the compiler happy.</li>
<li>I've read from countless sources that you don't use exceptions to control the flow of the program; you use them for <em>exceptional</em> circumstances.</li>
</ol>
<p>My question is: is there a way to please the compiler in this situation? I <em>have</em> to catch that FileNotFoundException, so using File.exists() won't really solve my problem. Am I doing things backwards, or is this just how Java rolls?</p>

2,655,829 | 2,655,830 | C++ : Aliases in function argument | <p>I have an issue with the use of aliases in function arguments. Here is my problem.</p>
<p>Let's consider this function definition</p>
<pre><code>void thisIsSparta(int& number){
...
}
</code></pre>
<p>at call time, it works perfectly well with the following code :</p>
<pre><code>int king = 1;
thisIsSparta(king);
</code></pre>
<p>but I have a mismatch error when I try this :</p>
<pre><code>thisIsSparta(1);
</code></pre>
<p>I can easily guess that the error occurs because there is simply no variable to alias, hence the error. However, I don't want the programmer to worry about using only one of the two approaches, this second function call should work as fine !</p>
<p>The only solution I see is to create another function with no alias argument, in addition to the first one :</p>
<pre><code>void thisIsSparta(int number){
}
</code></pre>
<p>But this would result in an awful code duplication, and I'm not a huge fan of this. </p>
<p>Furthermore, the program could decide to use this second definition instead of the former when I use a variable. I then loose the interest of the alias, whose purpose is to avoid variable copy.</p>
<p>Does anyone have a solution to my problem ? Indeed, this is a simplified example, in practice I have a generic type in argument for this function, and it could be arbitrarily big. This is why I'd like to use an alias to avoid copy.</p>

5,604,662 | 5,604,663 | how to iterate from a specific point in a sequence (Python) | <p><strong>[Edit]</strong></p>
<p>From the feedback/answers I have received, I gather there is some confusion regarding the original question. Consequently, I have reduced the problem to its most rudimentary form</p>
<p>Here are the relevant facts of the problem:</p>
<ol>
<li>I have a sorted sequence: <strong>S</strong></li>
<li>I have an item (denoted by <strong><em>i</em></strong>) that is GUARANTEED to be contained in <strong>S</strong></li>
<li>I want a <strong>find()</strong> algorithm that returns an iterator (<strong><em>iter</em></strong>) that points to <strong><em>i</em></strong></li>
<li>After obtaining the iterator, I want to be able to iterate FORWARD (BACKWARD?) over the elements in <strong><em>S</em></strong>, starting FROM (and including) <strong><em>i</em></strong></li>
</ol>
<p>For my fellow C++ programmers who can also program in Python, what I am asking for, is the equivalent of:</p>
<pre><code>const_iterator std::find (const key_type& x ) const;
</code></pre>
<p>The iterator returned can then be used to iterate the sequence. I am just trying to find (pun unintended), if there is a similar inbuilt algorithm in Python, to save me having to reinvent the wheel. </p>
