    <p>I have several columns of data in a csv file. I was able to isolate the column I want, but now I need to delete "|" and "&amp;" symbols contained in the column. Can anyone help me out? The relevant code is as follows: </p> <pre><code>// CSVRead.java //Reads a Comma Separated Value file and prints its contents. import java.io.*; import java.util.Arrays; import java.util.ArrayList; import java.util.List; import java.util.regex.*; public class CSVRead{ public static void main(String[] arg) throws Exception { BufferedReader b1 = new BufferedReader(new FileReader("Reactions.csv")); BufferedWriter b2 = new BufferedWriter(new FileWriter("Write1.txt")); BufferedWriter b3 = new BufferedWriter(new FileWriter("Write2.txt")); Pattern p1 = Pattern.compile("[+]"); Pattern p3 = Pattern.compile("\t"); Pattern p2 = Pattern.compile("&lt;=&gt;"); Pattern p4 = Pattern.compile(" "); Pattern p5 = Pattern.compile("RSP_[0-9][0-9][0-9][0-9]"); ArrayList&lt;String&gt; reactions = new ArrayList&lt;String&gt;();//List to hold all reactions ArrayList&lt;String&gt; reactionID = new ArrayList&lt;String&gt;();//List to hold all reactions ArrayList&lt;String&gt; genes = new ArrayList&lt;String&gt;();//List to hold all genes String strRead; String strWrite; while ((strRead=b1.readLine())!=null) { String splitarray[] = strRead.split("\t"); String firstentry = splitarray[0]; String secondentry = splitarray[7]; b3.write(secondentry); b3.newLine(); } b2.close(); b3.close(); } //main() } // CSVRead </code></pre> <p>I think I might have to use the expression:</p> <pre><code>genes.add(splitarray[7].replace("|","")); </code></pre> <p>for example. But I'm not sure where to put it or if it's correct. Thanks for you help,</p> <p>Kbball</p>

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.
