[英]XML line break character entity and Python encoding
I have the following line of code in a python script:我在 python 脚本中有以下代码行:
dep11 = ET.SubElement(dep1, "POVCode").text = "#declare lg_quality = LDXQual;
#if (lg_quality = 3)
#declare lg_quality = 4;
#end"
My question is in regards to the 

我的问题是关于


character.特点。 I want to see this character entity in the XML output, but the first ampersand keeps getting replaced with the
&
我想在 XML 输出中看到这个字符实体,但第一个 & 符号不断被
&
替换&
character entity, which creates the nonsense character entity 

字符实体,它创建无意义的字符实体


. .
I am encoding the file as utf-8
.我将文件编码为
utf-8
。
import xml.etree.ElementTree as ET
...
with open("LGEO.xml", "wb") as f:
tree.write(f, "utf-8")
And I end up with:我最终得到:
<POVCode>#declare lg_quality = LDXQual;&#x0A;#if (lg_quality = 3)&#x0A;#declare lg_quality = 4;&#x0A;#end</POVCode>
Not sure what I'm doing wrong.不知道我做错了什么。

I am trying to implement the solution found here that @mzjn pointed out.我正在尝试实施@mzjn 指出的此处找到的解决方案。
How to output XML entity references 如何输出 XML 实体引用
I have six lines of code:我有六行代码:
dep11 = ET.SubElement(dep1, "POVCode")
dep21 = ET.SubElement(dep2, "POVCode")
dep11.text = "#declare lg_quality = LDXQual;&
#if (lg_quality = 3)&
#declare lg_quality = 4;&
#end"
dep21.text = "#declare lg_studs = LDXStuds;&
"
ET.tostring(dep11).replace('&&', '&')
ET.tostring(dep21).replace('&&', '&')
I get no error, but the result is not any different than before when I write
the tree.我没有收到任何错误,但结果与我
write
树时的结果没有任何不同。
Again I am stuck.我又被卡住了。
What I eventually did was use the standard Python write
function instead of using ElementTree's own write
function.我最终做的是使用标准的 Python
write
函数,而不是使用 ElementTree 自己的write
函数。
text = ET.tostring(root).replace("&&", "&")
with open("LGEO.xml", "wb") as f:
f.write(text.encode("utf-8"))
The above is the last step in the Python code.以上是Python代码的最后一步。 I don't know if there are disadvantages to converting the root object to a string like this.
不知道把根对象转换成这样的字符串有没有坏处。 It could be slower but it works for me.
它可能会更慢,但它对我有用。
