Using java i try to replace occurence of certain string with other one. It works in most of the cases. But sometimes that certain string is not replaced in the given content. When i search that certain string in the given content using indexOf method, i can correctly get the index of that String. But when i use replaceFirst method to replace that String, the operation ends with unsuccess. Then i tried to replace using following in order to escape from escape characters. <pre><code>cont = Pattern.compile(str, Pattern.LITERAL).matcher(cont) .replaceFirst(Matcher.quoteReplacement("replace string")) </code></pre> Lets us take below content as example <blockquote> For the pictures of animal please visit this site <a href="http://www.example.net/animals/cat_345_456.JPG" rel="nofollow">http://www.example.net/animals/cat_345_456.JPG</a> . Also more details visit this link also <a href="http://www.moredetails.com/example/imgs/nwr_1453446_83223_429054_1603367_42.PNG?Id=1450686&lid=423454&idp=4402767&ps=4563223&circle=4&type=2&zw=264&zh=150&v=5&url=NA&uid=" rel="nofollow">http://www.moredetails.com/example/imgs/nwr_1453446_83223_429054_1603367_42.PNG?Id=1450686&lid=423454&idp=4402767&ps=4563223&circle=4&type=2&zw=264&zh=150&v=5&url=NA&uid=</a> . Thanks visiting us. </blockquote> In the above content First i assign str with value of <a href="http://www.example.net/animals/cat_345_456.JPG" rel="nofollow">http://www.example.net/animals/cat_345_456.JPG</a> and then i call replace first method. In this case expected string replaces correctly. Then now i assign str with value of <a href="http://www.moredetails.com/example/imgs/nwr_1453446_83223_429054_1603367_42.PNG?Id=1450686&lid=423454&idp=4402767&ps=4563223&circle=4&type=2&zw=264&zh=150&v=5&url=NA&uid=" rel="nofollow">http://www.moredetails.com/example/imgs/nwr_1453446_83223_429054_1603367_42.PNG?Id=1450686&lid=423454&idp=4402767&ps=4563223&circle=4&type=2&zw=264&zh=150&v=5&url=NA&uid=</a> and i call replace first method. But this time it doesn't got replaced. But when i use String.indexof method it correctly gives index number of that String. Am i missing anything? Please help. Thanks in advance.

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.
