Translator Framework issue

salarmehr · August 12, 2012

Consider Following markup:
<div>
<span>A</span>
B
</div>

I want fetch "B" using translator framework.
I tried followings all failed:
date : FW.Xpath("//div/text()") // returns null
date : FW.Xpath("//div/").text() // returns AB

How can I fetch just 'B'?

That's a tough construct to parse. You could fetch A and fetch AB, and then chop the length of A from the front of AB.

@fbennett Can you please give me some code? I can not run anything in FS.Scrapper()

I haven't used the framework yet, so I can't provide a worked example. But it can save to an item variable segment, so if the variable you're trying to fetch is "publisher", you should be able to do something like:


  item.publisher = (magic incantation for A)
  var tmp = item.publisher;
  item.publisher = (magic incantation for AB)
  item.publisher = item.publisher.slice(tmp.length);

More or less.

@fbennett Thanks. My concern is Translator Framework.
Without it we can easily use "//div/text()" xpath for fetching B

Again. you'll probably have better luck on zotero-dev.

I tried followings all failed:
date : FW.Xpath("//div/text()") // returns null
date : FW.Xpath("//div/").text() // returns AB

use
FW.Xpath("//div/text()").text()
Xpath() returns a node, so you need to get the text() regardless of what you put in the xpath.

@aurimas I also tried it (FW.Xpath("//div/text()").text())
it returns null
