Hi,
I have an elementtree question that probably reflects my inexperience
with xml processing (and/or with Python). The xml file is a stream of
the Spss Clementine program. Each stream consists of, among others,
nodes. Each nodes has properties, among which "tooltiptext" and
"label". I want to replace the contents of "label" to "tooltiptext".
Below is what I've cooked up till now. Could anyone give me some
pointers? Thanks a lot in advance!
from elementtree import ElementTree as ET
"""
Replace the empty text of the tooltipText tag with the text of the
label tag
Relevant part of the tree: stream/diagram/nodes/node/properties
Within properties, the tooltiptext tag is listed before the label tag.
"""
in_tree = ET.ElementTree(file="d:/jib/test.xml")
parent_map = dict((c, p) for p in in_tree.getiterator() for c in p)
def xml_read(parent_map):
for c, p in parent_map.iteritems():
if p.tag == "properties" and c.tag == "label":
yield c.text
##newnames = xml_read(parent_map)
##for newname in newnames:
## print newname
def xml_write(parent_map, in_tree):
newnames = xml_read(parent_map)
for c, p in parent_map.iteritems():
if p.tag == "properties" and c.tag == "toolTipText":
for newname in newnames:
print newname
c.text = newname
in_tree.write("d:/jib/out_xml.xml")
xml_write(parent_map, in_tree)
That looks a bit over-thought. If I've understood what you want,
something like below should do the job. It replaces the value of the id
attribute with the value of the colour attribute.
ATTR_TEST_STRING = '''
<root>
<title lang="en" encoding="utf-8">Document Title</title>
<category id="123" code="A">
<item id="A001" colour="red">Item A1</item>
<item id="A002" colour="blue">Item A2</item>
<item id="A003" colour="yellow">Item A3</item>
</category>
<category id="456" code="B">
<item id="B001" colour="pink">Item B1</item>
<item id="B002" colour="blue">Item B2</item>
<item id="B003" >Item B3</item>
</category>
<category id="789" code="C">
<item id="C001" colour="pink">Item C1</item>
<item id="C002" colour="orange">Item C2</item>
<item id="C003" colour="blue">Item C3</item>
</category>
</root>'''
from xml.etree import ElementTree as ET
xml = ET.fromstring(ATTR_TEST_STRING)
print('-------- before -------')
ET.dump(xml)
for elem in xml.getiterator():
if 'id' in elem.attrib and 'colour' in elem.attrib:
elem.set('id', elem.get('colour', ''))
print('-------- after -------')
ET.dump(xml)
