您好使用下面的代码片段,我在下面创建了一个xml,但我注意到:我在代码中使用的参数顺序与输出中的参数顺序不同,即<node y="-3749099.0" x="-45194.0" id="11542.0"/>
也应该是<node id="11542.0" x="-45194.0" y="-3749099.0"/>
输出不是下面所需的输出。有人可以告诉我怎么做:
val[0], val[1], val[2]
FIELD(id=str(val[0]), x=str(val[1]), y=str(val[2])),
代码段:
import lxml.etree
import lxml.builder
import xlrd
wb = xlrd.open_workbook("emme_nodes1.xls")
sh = wb.sheet_by_index(0)
tags = [n.replace(" ", "").lower() for n in sh.row_values(0)]
for row in range(1, sh.nrows):
val = sh.row_values(row)
E = lxml.builder.ElementMaker()
ROOT = E.network
DOC = E.nodes
FIELD = E.node
my_doc = ROOT(
DOC(
FIELD(id=str(val[0]), x=str(val[1]), y=str(val[2])),
)
)
print lxml.etree.tostring(my_doc, pretty_print=True)
输出:
<network>
<nodes>
<node y="-3748681.0" x="-45333.0" id="11543.0"/>
</nodes>
</network>
<network>
<nodes>

<nodes>
<node y="-3749805.0" x="-45485.0" id="11549.0"/>

期望的输出:

<node id="11542.0" x="-45194.0" y="-3749099.0"/>
<node id="11543.0" x="-45333.0" y="-3748681.0"/>

我终于找到了这个解决方案,而且效果很好
import xlrd
from lxml import etree
root = etree.Element('network')
root.set('name', 'Network')
tree = etree.ElementTree(root)
name = etree.Element('nodes')
root.append(name)
wb = xlrd.open_workbook("emme_nodes1.xls")
sh = wb.sheet_by_index(0)
for row in range(1, sh.nrows):
val = sh.row_values(row)
element = etree.SubElement(name, 'node')
element.set('id', str(int(val[0])))
element.set('x', str(val[1]))
element.set('y', str(val[2]))
print etree.tostring(root,pretty_print=True)
