Question

I have a large HTML String which contains some lines before the actual HTML code which are empty HTML and are not actually needed.

messageContent will contain something like:

        <td width="35"><br /> </td> 
        <td width="1"><br /> </td> 
        <td width="18"><br /> </td> 
        <td width="101"><br /> </td> 
        <td width="7"><br /> </td> 
        <td rowspan="21" colspan="16" width="689">Geachte&nbsp;heer/mevrouw,<br /> &nbsp;<br /> Wij&nbsp;hebben&nbsp;uw&nbsp;inzending&nbsp;ontvangen&nbsp;en&nbsp;gecontroleerd.&nbsp;Hierbij&nbsp;het&nbsp;verslag&nbsp;van&nbsp;de&nbsp;controle.<br /> &nbsp;<br />

I want to remove/replace everything before the line which contains ‘Geachte’, ‘ heer’ and ‘ mevrouw’.

As output I would like to keep only:

        <td rowspan="21" colspan="16" width="689">Geachte&nbsp;heer/mevrouw,<br /> &nbsp;<br /> Wij&nbsp;hebben&nbsp;uw&nbsp;inzending&nbsp;ontvangen&nbsp;en&nbsp;gecontroleerd.&nbsp;Hierbij&nbsp;het&nbsp;verslag&nbsp;van&nbsp;de&nbsp;controle.<br /> &nbsp;<br />

I thought I would use a BufferedReader to loop trough the text line by line:

try {
            reader = new BufferedReader(
                    new StringReader(messageContent));
        } catch (Exception failed) { }


        try {
            while ((string = reader.readLine()) != null) {

                if ((string.length() > 0) && (string.contains("Geachte"))) {
                    //remove all lines before this string
                }
            }
        } catch (IOException e) { }

How do I achieve this?

Answer 1

This code will do it.

public String cutText(String messageContent){
    boolean matchFound = false;
    StringBuilder output = new StringBuilder();
    try {
        reader = new BufferedReader(
                new StringReader(messageContent));
    } catch (Exception failed) { failed.printStacktrace(); }


    try {
        while ((string = reader.readLine()) != null) {

            if ((string.length() > 0) && (string.contains("Geachte"))) {
               matchFound = true;
            }
            if(matchFound){
                 output.append(string).append("\\n");
            }
        }
     } catch (IOException e) { e.printStacktrace();}
     return output.toString();
}
