美化在 xml 中添加额外的行
prettify adding extra lines in xml
我正在使用 Prettify 使我的 XML 文件可读。我正在将一些新信息添加到一个删除的 XML 文件中,但是当我将它保存到一个文件中时,我在两行之间得到了额外的行。有没有办法删除这些行?下面是我使用的代码
import xml.etree.ElementTree as xml
import xml.dom.minidom as minidom
from lxml import etree
def prettify(elem):
rough_string = xml.tostring(elem, 'utf-8')
reparsed = minidom.parseString(rough_string)
return reparsed.toprettyxml(indent="\t")
cid = "[123,123,123,123,123]"
doc = xml.parse('test.xml')
root = doc.getroot()
root.getchildren().index(root.find('card'))
e = xml.Element('card')
e.set('id', cid)
n = xml.SubElement(e, "name")
n.text = "FOLDER"
r = xml.SubElement(e, "red")
r.text = "FILE.AVI"
g = xml.SubElement(e, "green")
g.text = "FILE.AVI"
b = xml.SubElement(e, "blue")
b.text = "FILE.AVI"
root.insert(0, e)
doc2 = prettify(root)
with open("testnew.xml", "w") as f:
f.write(doc2)
下面是我在文件中得到的内容
<data>
<card id="[123,123,123,123,123]">
<name>FOLDER</name>
<red>FILE.AVI</red>
<green>FILE.AVI</green>
<blue>FILE.AVI</blue>
</card>
<card id="[000,000,000,000,000]">
<name>Colours</name>
<red>/media/usb/cow.avi</red>
<green>/media/usb/pig.avi</green>
<blue>/media/usb/cat.avi</blue>
</card>
</data>
输入文件 "test.xml" 看起来像
<data>
<card id="[000,000,000,000,000]">
<name>Colours</name>
<red>/media/usb/cow.avi</red>
<green>/media/usb/pig.avi</green>
<blue>/media/usb/cat.avi</blue>
</card>
</data>
新添加的内容打印正常。删除现有文本的任何 "prettification" 即可解决问题
添加
for elem in root.iter('*'):
if elem == e:
print "Added XML node does not need to be stripped"
continue
if elem.text is not None:
elem.text = elem.text.strip()
if elem.tail is not None:
elem.tail = elem.tail.strip()
调用前
doc2 = prettify(root)
