    <p>I tried many ways to do this. And I am totally new to Regular expression. I want to replace all img src link to other link.</p> <p>My html file just are like this:</p> <pre><code>&lt;img src="01"&gt;&lt;/img&gt;&lt;img src="02"&gt;&lt;/img&gt;&lt;img src="03"&gt;&lt;/img&gt; </code></pre> <p>or it would be like this:</p> <pre><code>&lt; img src = "01"&gt;&lt;/img&gt;&lt; img src="02"&gt;&lt; img src = "03"&gt;&lt;/img&gt; </code></pre> <p>There might be space or just without "<code>&lt;/img&gt;</code>"</p> <p>and I want them be like this way:</p> <pre><code>&lt;div&gt;&lt;p&gt;&lt;DIV class="a"&gt;&lt;img src="01"&gt;&lt;/img&gt;&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;p&gt;&lt;DIV class="a"&gt;&lt;img src="02"&gt;&lt;/img&gt;&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;p&gt;&lt;DIV class="a"&gt;&lt;img src="03"&gt;&lt;/img&gt;&lt;/p&gt;&lt;/div&gt; </code></pre> <p>and I use this to get the img src link:</p> <pre><code> Pattern p = null; Matcher m = null; p = Pattern.compile("&lt;img[^&gt;]*src\\s*=\\s*\"([^\"]*)"); m = p.matcher(mystr); while (m.find()) { imgIDList.add(m.group(1)); } </code></pre> <p>and I made the str list to replace: ArrayList imgList4Replace = new ArrayList();</p> <p>and I use this to excuse replace :</p> <pre><code> mystr.replace(("&lt;img[^&gt;]*src\\s*=\\s*\""+imgListReplaceOriginal.get(nIndex)+"([^\"]*)"), imgList4Replace.get(nIndex)+"$2"); </code></pre> <p>it just don't work. I've spent so much time to test.</p> <p>And need your help. Thank you very much.</p>

    1. CO[String.replace](http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#replace%5C%28java.lang.CharSequence,%20java.lang.CharSequence%5C%29) method doesn't apply regex. You should use [replaceAll](http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#replaceAll%28java.lang.String,%20java.lang.String%29) or [replaceFirst](http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#replaceFirst%28java.lang.String,%20java.lang.String%29) instead

    2. COAs a side note - images shouldn't have a closing tag. They should always be self closing: `<img src="whatever.jpg" />`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
