    <p>I have the following string with separate delimiters that needs to be parsed out and I am running into a bit of a wall at the moment.</p> <p><em>example</em>:</p> <p><strong>category 1---category 2;subgroup 1||subgroup 2---subgroup 1;value 1||value2---value 3</strong></p> <p>I wanted to re-arrange into the following grouping:</p> <p><strong>category 1;subgroup 1;value1;subgroup 2;value 2;category 2;subgroup 1;value1</strong></p> <p>The "---" delimiter separates a category and its values. The "||" delimiter separates fields belonging to the same category The ";" delimiter separates the field types (category; subgroup; value) There can be N categories of which they can have N subgroups.<br> each value is associated 1:1 with its subgroup</p> <p>The first pass through works fine but once I hit category 2 everything nulls out. I know I'm missing something obvious but I'm a little hazy right now and Java is not my first language. Here is what I have so far (sans delimiters)</p> <pre><code>StringBuilder result = new StringBuilder(); String categoryArray[] = category.split("---"); String subGroupArray[] = subgroup.split("---"); String valueArray[] = value.split("---"); for (int counter=0; counter&lt;categoryArray.length;counter++){ String categoryArray2[] = categoryArray[counter].split("\\|\\|"); String subGroupArray2[] = subGroupArray[counter].split("\\|\\|"); String valueArray2[] = valueArray[counter].split("\\|\\|"); result.append(categoryArray[counter].trim()); for (int counter2=0; counter2&lt;subGroupArray2.length;counter2++){ result.append(subGroupArray2[counter2].trim()); result.append(valueArray2[counter2].trim()); } result.append("||"); } return result; </code></pre> <p><br><br> Any help or optimized approaches would certainly be appreciated!</p>

    2. COI can't understand the intended relationships between categories, subgroups and values and how your notation convention expresses them in the first string. Can you clarify in your question?

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.
