我正在编辑由第三方提供的XML文件。 XML用于重新创建和整个环境,并且可以编辑XML以传播更改。我能够通过命令行选项查找我想要更改的元素并保存XML,但是特殊字符正在被转义,我需要保留特殊字符。例如,它正在改变>到$ gt;在.write操作期间的文件中。这会影响XML文档的所有出现,而不仅仅是节点元素(我认为这就是它所称的)以下是我的代码:
import sys
from lxml import etree
from optparse import OptionParser
def parseCommandLine ():
usage = "usage: %prog [options] arg"
parser = OptionParser(usage)
parser.add_option("-f","--file",dest="filename",
help="Context File name including full path", metavar="CONTEXT_FILE")
parser.add_option("-k","--key",dest="key",
help="Key you are looking for in Context File i.e s_isAdmin", metavar="s_someKey")
parser.add_option("-v","--value",dest="value",
help="The replacement value for the key")
if len(sys.argv[1:]) < 3:
print len(sys.argv[1:])
parser.print_help()
sys.exit(2)
(options, args) = parser.parse_args()
return options.filename, options.key, options.value
Filename, Key, Value=parseCommandLine()
parser_options=etree.XMLParser(attribute_defaults=True, dtd_validation=False, strip_cdata=False)
doc = etree.parse(Filename, parser_options ) #Open and parse the file
print doc.findall("//*[@oa_var=%r]" % Key)[0].text
oldval = doc.findall("//*[@oa_var=%r]" % Key)[0].text
val = doc.findall("//*[@oa_var=%r]" % Key)[0]
val.text = Value
print 'old value is %s' % oldval
print 'new value is %s' % val.text
root = doc.getroot()
doc.write(Filename,method='xml',with_tail=True,pretty_print=False)
原始文件包含:
tf.fm.FulfillmentServer&gt;&gt; / s_u01 /应用程序/ applmgr / F
已保存的版本正在替换为:
tf.fm.FulfillmentServer >> /s_u01/app/applmgr/f
我一直试图在解析端的输出端DTD验证中弄乱了pretty_print,我很难过。
以下是已更改文件和原始文件的差异:
我仅更新了s_cookie_domain。

我唯一能想到的是强制解析器将你修改的节点视为cdata块(因为解析器正在明显改变xml标签的右括号)。请尝试使用val.text = etree.CDATA(Value)
代替val.text = Value
。
