How are DOM objects passed by ZU.processDocuments?

runkelcorey

Hi all, I'm cooking up a web translator and have encountered difficulties when multiple items are passed to scrape().

I've located the problem in a ZU.xpath(**xpath**, "@href") expression that evaluates as a string when doWeb() calls scrape(doc, url) but evaluates as an Object when doWeb calls ZU.processDocuments(articles, scrape). This problem first appears at line 84 of the link below. Any ideas on how to get around this? This translator is my first foray into JavaScript, so there may be a simple Object method that I'm not aware of.

Thanks as always.

Attempted solutions:
* JSON.stringify(ZU.xpath(.))
* ZU.xpath(.).toString()
* ZU.xpath(.)[0]

How I localized to ZU.xpath():
* itemType() works when doWeb() calls scrape(doc, url)
* not a problem with calling other functions when doWeb() calls ZU.processDocuments() since I can call getLocale() just fine
* declaring each item to be [Zotero] type document does not solve any problems

ZU.xpath should never return a string, always an object. Use ZU.xpathText(doc, '.') if you want a string, or use ZU.xpath(doc, '.')[0].textContent

Also, please post further translator questions to zotero-dev, we try to keep technical discussion there:

Thanks, this would explain why I couldn't find translator problems!
