Hi all,
I would like to ask about the possibility of reading xml files in the new versions (2023) of Civil 3D and Revit, where CPython 3 is available. Does anyone have any experience they are willing to share?
Regards
Lukas

to reading pure XML files, we can use ElementTree XML API (compatible both engine)

    pf_path = System.Environment.GetFolderPath(System.Environment.SpecialFolder.ProgramFilesX86)
    sys.path.append(pf_path + '\\IronPython 2.7\\Lib')
	
import xml.etree.ElementTree as ET
import xml.dom.minidom

out = []
path_xml = IN[0]
try:
	with open(path_xml, 'r') as o:
		txt = o.read()
except:
	with io.open(path_xml, 'r', encoding='utf-8') as o:
		txt = o.read()
		
root = xml.etree.ElementTree.fromstring(txt)    
xmlBefore = ET.tostring(root)
mySearchTags = root.findall(".//Eclairage")
for myTag in mySearchTags:
    childs = myTag.getchildren()
    for node in childs:
       out.append([myTag.tag, node.tag])

OUT =  out

@c.poupin Hi, I try using your code but it returns me an empty list. Do you know why?

Hi @Luffy11 ,
probably you haven’t element node named “Eclairage” in your XML file, you need to adapt the code

the document is here

@c.poupin Thank you for replying me but I don’t know code. Is there any node in Dynamo with similar function?

Before there was the LunchBox package, but the development was stopped, now I don’t know

@c.poupin yeah, I’ve installed LunchBox package but can’t find the nodes relating to XML. Let me find another way. Thank you for your reply.
