<h1>Use Regular Expressions to Search and Replace in Coda or TextMate</h1>
|
||
|
||
<p class="posted text-light">4th November 2010</p>
|
||
|
||
<p>As in <a href="/blog/add-taxonomy-term-multiple-nodes-using-sql/" title="Quickly adding a taxonomy term to multiple nodes using SQL">the original post</a>, I'd generated a list of node ID values, and needed to add structure the SQL update statment formatted in a certain way. However, I changed my inital query slightly to out put the same nid value twice.</p>
|
||
|
||
<pre><code class="language-sql">SELECT nid, nid FROM node WHERE TYPE = 'blog' ORDER BY nid ASC;
|
||
</code></pre>
|
||
|
||
<p>Then, I could select all of the returned rows, copy the values, and paste them into Coda:</p>
|
||
|
||
<p>As before, I needed my SQL update statement to be in the following format:</p>
|
||
|
||
<pre><code class="language-sql">INSERT INTO term_node VALUE (nid, vid, tid), (nid2, vid2, tid);
|
||
</code></pre>
|
||
|
||
<p>As I mentioned previously, the nid and vid values are the same for each node, and the tid will remain constant. In this case, the tid value that I needed to use was '63'.</p>
|
||
|
||
<p>So, using the 'Find and Replace' function within Coda, combined with <a href="http://en.wikipedia.org/wiki/Regular_expression">regular expressions</a> (regex), I can easily format the values as needed. To begin with, I need to ensure that the RegEx search option is enabled, and that I'm using the correct escape character.</p>
|
||
|
||
<p>The first thing that I wanted to do was add the seperating comma between the two values. To do this, I
|
||
perform a search for <code>\s*\t</code>. This searches for everything that is whitespace AND is a tab value. I can then add the comma as the replacement for each result.</p>
|
||
|
||
<p>All 31 lines have been changed.</p>
|
||
|
||
<p>Next, I can use <code>\n</code> to target the lines between the rows. I'll replace it with the next comma, the number 63 (the tid value), the closing bracket, another comma, re-add the line and add the opening bracket.</p>
|
||
|
||
<p>The only two lines that aren't changed are the first and last, as they don't have any line breaks following them. I can complete these lines manually. Now all I need to do is add the beginning of the SQL update statement, then copy and paste it into Sequel Pro.</p>
