Chapter 1 Introduction

Page 7 - Regular Expressions

This was reported as Issue 5.

There was an error somewhere after final edition and printing. And an extra "A" slipped in to a code block:

A^\t+    Matches one or more Tab characters at the start of a string

should be

^\t+    Matches one or more Tab characters at the start of a string

This was reported as Issue 1.

A closing square bracket was mistakenly deleted during review:

 <![CDATA[
 Here you can ...
 ]>

Should be

 <![CDATA[
 Here you can ...
 ]]>

This was reported as Issue 2.

This is not an error by itself, but some people may have problem reproducing this.

 <![if IE 8.0]>
 <script>alert(1)</script>  // works on IE8
 <![endif]>

This code is supposed to work on Internet Explorer 8 mode. Depending on the doctype of the page, it could load your browser in other mode.

This was reported as Issue 3.

During edition some dashes were missed:

 <!-[if<img src=x onerror=alert(1)//]--> works! 
 <b>000</b> <!--[endif]->

should be

 <!--[if<img src=x onerror=alert(1)//]--> works! 
 <b>000</b> <!--[endif]-->

This was reported as Issue 4.

A closing angle bracket got lost during editing.

 <!--[if true && ><script>alert(1)</script]->
 000
 <!--[endif]->

should be

 <!--[if true && ><script>alert(1)</script>]->
 000
 <!--[endif]->
