Question

我正在努力通过Web API提取日志，到目前为止，在拉动日志时，它们会以下列格式返回（以下3个事件开始和结束。我的问题是循环每行的最佳方法是什么并连接它们，以便结果事件如下所示。

当前输出

Answer 1

如果这只是一个包含换行符的大型字符串对象，您只需删除它们即可：

import re
text = re.sub('\s*\n\s*', '', text)

要在</attack_headline>分隔符后面留下换行符，请尝试：

re.sub('(?<!<\/attack_headline>)\s*\n\s*', '',  x)

Answer 2

您可以使用：

oneline = "".join(multiline.split())

编辑1（我刚看到你的编辑） - 我会改变你的代码：

with open(filename, "r") as fo:
    result = []
    for line in fo.readlines():
        result.append(line.strip())
    return result

编辑2（我已经阅读了你对其他答案的评论） - 你可以这样做：

with open(filename, "r") as fo:
    partial = []
    for line in fo.readlines():
        if line.startswith("<"):
            yield "".join(partial)
            partial = []
        else:
            clean = line.strip()
            if clean:
                partial.append(clean)

Answer 3

import re
# remove all newline whitespace stuff as in answer given before:
text = re.sub(r'\s*\n\s*', '', text)
# break again at desired points:
text = re.sub(r'</attack_headlines>', '</attack_headlines>\n', text)

在Python中连接多行（文本格式）
