With help of relevant tutorial I cobbled up a script using XML::twig for extraction of 2 values (disparate branches of the tree of each record) from quite big(100 000 records) and quite structured database output. XML is new for me but I somehow believed that it is not "proper" to use regular expressions for this propose when there is "structure" a and set of tools for manipulation with it. But then I started to think that there is no reason to discard using regular expressions, especially when I need just a few values from each record. Are there some general guidelines when to use RE or some XML parsing tool? And known pitfalls of either approach? tx karpatov

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
