我有一个看起来像这样的xml:
<root>
<G>
<G1>1</G1>
<G2>some text</G2>
<G3>some text</G3>
<GP>
<GP1>1</GP1>
<GP2>a</GP2>
<GP3>a</GP3>
</GP>
<GP>
<GP1>2</GP1>
<GP2>b</GP2>
<GP3>b</GP3>
</GP>
<GP>
<GP1>3</GP1>
<GP2>c</GP2>
<GP3>c</GP3>
</GP>
</G>
<G>
<G1>2</G1>
<G2>some text</G2>
<G3>some text</G3>
<GP>
<GP1>1</GP1>
<GP2>aa</GP2>
<GP3>aa</GP3>
</GP>
<GP>
<GP1>2</GP1>
<GP2>bb</GP2>
<GP3>bb</GP3>
</GP>
<GP>
<GP1>3</GP1>
<GP2>cc</GP2>
<GP3>cc</GP3>
</GP>
</G>
<G>
<G1>3</G1>
<G2>some text</G2>
<G3>some text</G3>
<GP>
<GP1>1</GP1>
<GP2>aaa</GP2>
<GP3>aaa</GP3>
</GP>
<GP>
<GP1>2</GP1>
<GP2>bbb</GP2>
<GP3>bbb</GP3>
</GP>
<GP>
<GP1>3</GP1>
<GP2>ccc</GP2>
<GP3>ccc</GP3>
</GP>
</G>
</root>
我试图将这个xml转换为一个名为“G”的嵌套字典:
{ 1: {G1: 1,
G2: some text,
G3: some text,
GP: { 1: {GP1: 1,
GP2: a,
GP3: a},
2: {GP1: 2,
GP2: b,
GP3: b},
3: {GP1: 3,
GP2: c,
GP3: c}}
},
2: {G1: 2,
G2: some text,
G3: some text,
GP: { 1: {GP1: 1,
GP2: aa,
GP3: aa},
2: {GP1: 2,
GP2: bb,
GP3: bb},
3: {GP1: 3,
GP2: cc,
GP3: cc}}
},
3: {G1: 3,
G2: some text,
G3: some text,
GP: { 1: {GP1: 1,
GP2: a,
GP3: a},
2: {GP1: 2,
GP2: bbb,
GP3: bbb},
3: {GP1: 3,
GP2: ccc,
GP3: ccc}}
}
}
我的代码可以很好地获得直接在“G”下的所有元素,所以G1,G2等,但是对于GP我要么只得到一条记录,要么我得到所有这些但是它复制了同样的东西我要么在字典中的单个GP下获得所有9个GP元素。这是我的代码:
f = 'path to file'
tree = ET.parse(f)
root = tree.getroot()
self.tree = tree
self.root = root
gs = len(self.tree.getiterator('G'))
g = {}
for i in range(0, gs):
d = {}
for elem in self.tree.getiterator('G')[i]:
if elem.text == "\n " and elem.tag not in ['GP']:
dd = {}
for parent in elem:
if parent.text == "\n ":
ddd = {}
for child in parent:
ddd[child.tag] = child.text
dd[parent.tag] = ddd
else:
dd[parent.tag] = parent.text
d[elem.tag] = dd
else:
d[elem.tag] = elem.text
g[i+1] = d
# Build GP
count = 0
gp = {}
for elem in self.tree.getiterator('GP'):
d = {}
for parent in elem:
if parent.text == "\n ":
dd = {}
for child in parent:
dd[child.tag] = child.text
d[parent.tag] = dd
else:
d[parent.tag] = parent.text
count += 1
gp[count] = d
g["GP"] = gp
