Tree model markup builder.
Project description
Pure pythonic tree structure model builder.
Enter tree nodes with python’s contextmanagers.
Cast the tree to given markup (basically it’s suited for XML).
Enjoy 1:1 translation from python to given markup.
XML Example
from xplant import xml_plant
x = xml_plant()
with x.node("section_a", attribute_1=1):
with x.node("nested_1", empty=True):
pass
with x.node("nested_2"):
x.comment("Can handle also comments.")
for number in range(3):
x.leaf("a number {:02}".format(number), num=number)
print(x)Will give:
<?xml version="1.0" encoding="utf-8"?>
<section_a attribute_1="1">
<nested_1 empty="true"></nested_1>
<nested_2>
<!-- Can handle also comments. -->
<a number 00 num="0" />
<a number 01 num="1" />
<a number 02 num="2" />
</nested_2>
</section_a>HTML generation Example
