本文介绍了“不在实体开始处的XML或文本声明:第2行,第0列,”调用ElementTree.parse时的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

在下面的简单示例中,ElementTree.parse() 失败,并显示错误

ElementTree.parse() fails in the simple example below with the error


xml.etree .ElementTree.ParseError:XML或文本声明不在实体的开头:第2行,第0列

xml.etree.ElementTree.ParseError: XML or text declaration not at start of entity: line 2, column 0

XML看起来有效且代码很简单,那么我在做什么错了?

The XML looks valid and the code is simple, so what am I doing wrong?

xmlExample = """
<?xml version="1.0"?>
<data>
    stuff
</data>
"""
import io
source = io.StringIO(xmlExample)
import xml.etree.ElementTree as ET
tree = ET.parse(source)


推荐答案

在XML字符串的开头有一个换行符,将其删除:

You have a newline at the beginning of the XML string, remove it:

xmlExample = """<?xml version="1.0"?>
...

或者,您可能只是 strip() XML字符串:

Or, you may just strip() the XML string:

source = io.StringIO(xmlExample.strip())

作为旁注,您不必创建类似文件的缓冲区,而使用 .fromstring() 相反:

As a side note, you don't have to create a file-like buffer, and use .fromstring() instead:

root = ET.fromstring(xmlExample)
