title: `gulp-replace` is only replacing some, but not all, of the targets
body: <p><strong><code>gulp-replace</code> isn't replacing everything that it should.</strong></p>
  
  <p>I'm trying to replace <code>&lt;li&gt;</code>'s and it's only removing some of them. When I add a list item it is successfully removed but the ones in original document are not. This is even true if I copy/paste the <code>&lt;li&gt;</code> into a new file.</p>
  
  <p><strong>test.html</strong> is the source document.</p>
  
  <pre><code>&lt;h2&gt;Copied from source:&lt;/h2&gt;
  &lt;ul&gt;
      &lt;li class="Bullets"&gt;Athletics&lt;/li&gt;
      &lt;li class="Bullets"&gt;Burglary&lt;/li&gt;
  &lt;/ul&gt;
  
  &lt;h2&gt;Entered in Sublime Text 2&lt;/h2&gt;
  &lt;ul&gt;
      &lt;li&gt;Lorem ipsum dolor sit amet.&lt;/li&gt;
      &lt;li&gt;Eos ipsam in dolorum odio!&lt;/li&gt;
      &lt;li&gt;Illum asperiores eligendi, iure tempora.&lt;/li&gt;
      &lt;li&gt;Reprehenderit blanditiis repudiandae ex eligendi.&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p><strong>test.md</strong> is what is outputted. Note that the <code>&lt;li&gt;</code>'s that I entered in Sublime Text are removed but the others are not.</p>
  
  <pre><code>&lt;h2&gt;Copied from source:&lt;/h2&gt;

      &lt;li class="Bullets"&gt;Burglary&lt;/li&gt;
  &lt;/ul&gt;

      Eos ipsam in dolorum odio!&lt;/li&gt;
      Illum asperiores eligendi, iure tempora.&lt;/li&gt;
      Reprehenderit blanditiis repudiandae ex eligendi.&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p><strong>gulpfile.js</strong></p>
  
  <pre><code>(function () {
  
    'use strict';
  
    var gulp = require('gulp');
    var replace = require('gulp-replace');
    var dest = require('gulp-dest');
  
    gulp.task('replace', function(){
      gulp.src(['source/*.html'])
        .pipe(replace('&lt;li&gt;',''))
        .pipe(dest('dest', {ext: '.md'}))
        .pipe(gulp.dest('./'));
    });
  
  })();
  </code></pre>
  
  <p>Any help is appreciated! Thank you!</p>
