  1. POremoving whitespaces in ActionScript 2 variables
    text
    copied!<p>let's say that I have an XML file containing this :</p> <pre><code>&lt;description&gt;&lt;![CDATA[ &lt;h2&gt;lorem ipsum&lt;/h2&gt; &lt;p&gt;some text&lt;/p&gt; ]]&gt;&lt;/description&gt; </code></pre> <p>that I want to get and parse in ActionScript 2 as HTML text, and setting some CSS before displaying it. Problem is, Flash takes those whitespaces (line feed and tab) and display it as it is.</p> <pre><code>&lt;some whitespace here&gt; lorem ipsum some text </code></pre> <p>where the output I want is</p> <pre><code>lorem ipsum some text </code></pre> <p>I know that I could remove the whitespaces directly from the XML file (the Flash developer at my workplace also suggests this. I guess that he doesn't have any idea on how to do this [sigh]). But by doing this, it would be difficult to read the section in the XML file, especially when lots of tags are involved and that makes editing more difficult.</p> <p>So now, I'm looking for a way to strip those whitespaces in ActionScript. I've tried to use PHP's <code>str_replace</code> equivalent (got it from <a href="http://snipplr.com/view/3369/strreplace/" rel="nofollow noreferrer">here</a>). But what should I use as a needle (string to search) ? (I've tried to put in <code>"\t"</code> and <code>"\r"</code>, don't seem to be able to detect those whitespaces).</p> <p>edit :</p> <p>now that I've tried to throw in <code>newline</code> as a needle, it works (meaning that newline successfully got stripped).</p> <pre><code>mystring = str_replace(newline, '', mystring); </code></pre> <p>But, newlines only got stripped once, meaning that in every consecutive newlines, (eg. a newline followed by another newline) only one newline can be stripped away.</p> <p>Now, I don't see that this as a problem in the <code>str_replace</code> function, since every consecutive character other than newline get stripped away just fine.</p> <p>Pretty much confused about how stuff like this is handled in ActionScript. :-s</p> <p>edit 2: </p> <p>I've tried str_replace -ing everything I know of, \n, \r, \t, newline, and tab (by pressing tab key). Replacing \n, \r, and \t seem to have no effect whatsoever.</p> <p>I know that by successfully doing this, my content can never have real line breaks. That's exactly my intention. I could format the XML the way I want without Flash displaying any of the formatting stuff. :)</p>
