    <p>I am trying to create a BASH script what would extract the data from HTML table. Below is the example of table from where I need to extract data:</p> <pre><code>&lt;table border=1&gt; &lt;tr&gt; &lt;td&gt;&lt;b&gt;Component&lt;/b&gt;&lt;/td&gt; &lt;td&gt;&lt;b&gt;Status&lt;/b&gt;&lt;/td&gt; &lt;td&gt;&lt;b&gt;Time / Error&lt;/b&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt;&lt;td&gt;SAVE_DOCUMENT&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.406 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;GET_DOCUMENT&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.332 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;DVK_SEND&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.001 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;DVK_RECEIVE&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.001 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;GET_USER_INFO&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.143 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;NOTIFICATIONS&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.001 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;ERROR_LOG&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.001 s&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;SUMMARY_STATUS&lt;/td&gt;&lt;td&gt;OK&lt;/td&gt;&lt;td&gt;0.888 s&lt;/td&gt;&lt;/tr&gt; &lt;/table&gt; </code></pre> <p>And I want the BASH script to output it like so:</p> <pre><code>SAVE_DOCUMENT OK 0.475 s GET_DOCUMENT OK 0.345 s DVK_SEND OK 0.002 s DVK_RECEIVE OK 0.001 s GET_USER_INFO OK 4.465 s NOTIFICATIONS OK 0.001 s ERROR_LOG OK 0.002 s SUMMARY_STATUS OK 5.294 s </code></pre> <p>How to do it?</p> <p>So far I have tried using the sed, but I don't know how to use it quite well. The header of the table(Component, Status, Time/Error) I excluded with grep using <code>grep "&lt;tr&gt;&lt;td&gt;</code>, so only lines starting with <code>&lt;tr&gt;&lt;td&gt;</code> will be selected for next parsing (sed). This is what I used: <code>sed 's@&lt;\([^&lt;&gt;][^&lt;&gt;]*\)&gt;\([^&lt;&gt;]*\)&lt;/\1&gt;@\2@g'</code> But then <code>&lt;tr&gt;</code> tags still remain and also it wont separate the strings. In other words the result of this script is:</p> <pre><code>&lt;tr&gt;SAVE_DOCUMENTOK0.406 s&lt;/tr&gt; </code></pre> <p>The full command of the script I'm working on is:</p> <pre><code>cat $FILENAME | grep "&lt;tr&gt;&lt;td&gt;" | sed 's@&lt;\([^&lt;&gt;][^&lt;&gt;]*\)&gt;\([^&lt;&gt;]*\)&lt;/\1&gt;@\2@g' </code></pre>

    1. CODoes it have to be a bash script? If you are on Linux, perhaps a Perl script would be an easier option. You could then use the [HTML::Parser](http://search.cpan.org/~gaas/HTML-Parser-3.68/Parser.pm) module, or similar.

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.
