[lxml] Xpath, span control and iterate inside xpath result.

Nov. 5, 2013

      Hello and many thanks for lxml module!

I am discovering its capabilities but I can hardly end up my first
parser, because of 2 issues.

First, I have a valid file.html to parse, here is an example:

<html>
	<body>
		<tbody>
		<tr>
		<td>
		<table id="tbHeaderImages">
			<span class="Title">
			BLO BLO
			<span style="color:red; font-weight:bold">BLU BLU</span>
			BLA BLA
			</span>
		<br>
		<br>
		Some texttext
		<br>
		...
		</table>
		</tbody>
	</body>
</html>

I have many documents each inside table:
for document in TREE.xpath('/html/body/table'):

Then, I want to extract each title:
title = document.xpath("./tr/td/span[@class = 'Title']/text()")

Problem 1: I get "BLO BLO" and "BLA BLA" whereas I would like 
"BLO BLO" and "BLU BLU" and "BLA BLA".

I have heard that I should get the value of the text from the first
node. Get the second node (not the text value) and use the .text
attribute to replace the text. But I do not really understand how to
manage it. Please may you give me an example.

Problem 2: I want also to extract "Some texttext" just after the span
class. Then, I have to trigger an event in an SAX like method. If you
agree with with how I could do such trick if I am already working in the
TREE.xpath('/html/body/table') ?

Many thanks for your help,
