How can I access the elements separated by comma in xml tags?
I need to store the elements separated by comma in xml tags
For example, these x and y coordinates:
<points> <point>558.000000,790.000000</point> <point>530.000000,829.000000</point> <point>567.000000,855.000000</point> <point>595.000000,815.000000</point> <point>558.000000,790.000000</point> </points> I tried something like this
x1, y1 = ((item.getElementsByTagName('points')[0]).getElementsByTagName('point')[0]).firstChild.data But got the following error
ValueError: too many values to unpack (expected 2) Any help in this will be appreciated.
I have recently work on accessing the XML tags and I prefer xml.dom.minidom library of python for this use.
The code for your above-mentioned XML tags in the question is:
import xml.dom.minidom as minidom name = "<points><point>558.000000,790.000000</point><point>530.000000,829.000000</point><point>567.000000," \ "855.000000</point><point>595.000000,815.000000</point><point>558.000000,790.000000</point></points> " point = [] xml_loaded = minidom.parseString(name) Points_Node = xml_loaded.getElementsByTagName("points") for Main_Node in range(len(Points_Node)): Point_Child = Points_Node[Main_Node].getElementsByTagName("point") for Child_Node in range(len(Point_Child)): point.append((Point_Child[Child_Node].firstChild.nodeValue).split(",")) print(point) The output for above-mentioned code is split with x and y coordinates and stored in an array as you requested in the question. The output can be seen below:
[['558.000000', '790.000000'], ['530.000000', '829.000000'], ['567.000000', '855.000000'], ['595.000000', '815.000000'], ['558.000000', '790.000000']] Hope this help, please let me know if this is what you want.
You could use
import xml.etree.ElementTree as ET data = """ <points> <point>558.000000,790.000000</point> <point>530.000000,829.000000</point> <point>567.000000,855.000000</point> <point>595.000000,815.000000</point> <point>558.000000,790.000000</point> </points> """ tree = ET.fromstring(data) for element in tree: x,y = element.text.split(",") print(x, y)
