Xpath Problem With Plex:s Xml-parser

Dev Community Dev/API Corner

I’m trying to parse a XML with XPath and get some strange results with Plex. It works in XPath Checker plugin for Firefox and on this site, http://www.mizar.dk/XPath/Default.aspx but not with Plex.



<br />
#When using isHTML = True no category has subcategories<br />
subCategories = XML.ElementFromURL('http://www.expressen.tv/2.2729?output=xmlMenuOutput', isHTML=False, cacheTime=0) <br />
<br />
#Does not work, but should return subcategories for category Sport, id = 2.2731<br />
subCat1 = subCategories.xpath('/root/category[id=2.2731]/subcategories/subcategory') <br />
<br />
#This one works, and returns subcategories for category Nyheter (News), id = 2.2729<br />
subCat2 = subCategories.xpath('/root/category[id=2.2729]/subcategories/subcategory') <br />


If i look at the xml both xpath-expressions should get a result but for some reason the subCat1 is empty.

So I'm wondering if there are anything wrong with the xml-parser that Plex uses and if there are any workaround for it?

Xml for category Nyheter (News) that works

I found a solution for it.



subcategories = subCategories.xpath('/root/category[id=\'' + id + '\']/subcategories/subcategory')

Glad you were able to figure it out, thanks for posting the solution you found!
