Preceding sibling return empty node - xpath

Question

In this example i have this code:
<table class="basicinfo" cellspacing="0">
<tr class="header">
<td colspan="3">
<div>
<h2 class="prod_card">Basic info</h2>
</div>
</td>
</tr>
<tr class="row2 item">
<td class="cell0">
<div>
Year
</div>
</td>
<td class="cell1">
<div>
2005
</div>
</td>
</tr>
<tr class="row3 item alt">
<td class="cell0">
<div>
Extra
</div>
</td>
<td class="cell1">
<div>
-
</div>
</td>
</tr>
</table>
Now, i want to get (for example) the year. I'm trying to get the next div content after the div with Year content.
I'm using this xpath without success:
//div[preceding-sibling::div = 'Year']
And anyone knows a good website to start learning xpath? Thanks in advance!

Answer 1

Following XPath
//div[parent::td/preceding-sibling::td//div[normalize-space()= 'Year']]
has the result
<div>2005</div>
Your XPath didn't work because the div you are looking for has not a div element as preceding-sibling but a td as parent. The preceding-sibling::td of this td contains a div which has the text "Year" - td//div. Using normalize-space() returns the text of this div without any spaces which can be necessary when checking for equality.
For reference: normalize-space(), and as you asked for good resources - I don't want to recommend anything special, but you should have a look at the resources mentioned at the info given on stackoverflow here: https://stackoverflow.com/tags/xpath/info (if not already done) and, for XPath axes, this is a good visualization: http://www.xmlplease.com/axis
