cURL和domDocument来解析html

Question

I only need a single value from a specific <td> in the DOM's nested tables. There are 7 tables one inside the other and that specific <td> is using a class called "LtrAligned".

How can I go about the DOM and see exactly which element do I need and what will bring me back the data I am looking for?

1. What are the methods used to retrieve the HTML that is between the tags ? like:

   <a href="abc.com">this is a link</a> /// retrieve the text value-> this is a link

2. how can I take out the value that is placed inside the tag, like:

   <a href="abc.com">this is a link</a> /// retrieve the href value-> abc.com

I get many errors going through the DOM because I don't know exactly what to look for. Is there a way to actually go about it step by step and reaching that exact <td> ?

Thanks!
