  1. POBasic Regex Practice

    copied!<p>A simple question I was unable to find any similar examples which did not recommend using outside libraries, I have an exercise in which we have mock data similar to HTML/XML and we are restricted to using only Java regex library to parse and manipulate it. We want to translate the data into a map. The format is:</p> <pre class="lang-none prettyprint-override"><code>&lt;key&gt; data words here &lt;/key&gt;... </code></pre> <p>...where each data word will be added to the map with the key separately, so the resulting map should look like this:</p> <pre class="lang-none prettyprint-override"><code>{key, data key, words key, here} </code></pre> <p>I have come up with some solutions which first find and store the key using a regex, then match the inside of the key tag, store that data in a string, tokenize it using a space and bracket delimiters, and loop through the resulting list to write to the map. Is there a more straightforward or elegant method of doing this where I could capture the key and an array/list of the data words using just regex and eliminating the use of the tokenizer?</p> <p>Some sample data below (notice there are no nested tags which makes this much simpler than parsing HTML):</p> <pre class="lang-none prettyprint-override"><code>&lt;author&gt; A. Cau, R. Kuiper, and W.-P. de Roever. &lt;/author&gt; &lt;title&gt; Formalising Dijkstra's development strategy within Stark's formalism. &lt;/title&gt; &lt;editor&gt; In C. B. Jones, R. C. Shaw, and T. Denvir, editors, &lt;/editor&gt; &lt;booktitle&gt; Proc. 5th. BCS-FACS Refinement Workshop, &lt;/booktitle&gt; &lt;date&gt; 1992. &lt;/date&gt; </code></pre> <p>(all on one line - line breaks added for readability)</p>
