我有一个来自Nose的html格式的测试报告文件。 我想在Python中从中提取文本的一些部分。我将在邮件部分的电子邮件中发送此邮件。
我有以下样本：

如果我在浏览器中打开文件，格式如下： 这是我想从html文件中提取的文本。
Class Fail Error Skip Success Total
Regression_TestCase 1 9 0 219 229
我该怎么办？以表格格式保存它会很好。 谢谢，Riaz
答案 0 :(得分：1)
您的示例html代码包含未打开的标签和没有打开标签的结束标签。我假设您只显示一个示例，并且您提取的文件格式如下：
<body>
<h1>Overview</h1>
<section>
<table>
<tr>
<th>Class</th>
<th class="failed">Fail</th>
<th class="failed">Error</th>
<th>Skip</th>
<th>Success</th>
<th>Total</th>
</tr>
<tr>
<td>Regression_TestCase</td>
<td class="failed">1</td>
<td class="failed">9</td>
<td>0</td>
<td>219</td>
<td>229</td>
</tr>
<tr>
<td><strong>Total</strong></td>
<td class="failed">1</td>
<td class="failed">9</td>
<td>0</td>
<td>219</td>
<td>229</td>
</tr>
</table>
</section>
</body>
您可以使用Etree模块将代码解析为xml。 编辑：将用于查找表格的方法更改为使用xpath并使其成为＆＃34; Total＆＃34;列将不会被打印。
编辑2：我现在使用正则表达式来提取代码中的所有表。小心使用它，因为它是一个非常脆弱的解决方案。如果有一个没有关闭表标记的打开表标记，那么它将在打开表标记之后提取所有文本并崩溃，因为生成的字符串将不是格式良好的xml。
import csv
import re
import xml.etree.ElementTree as ET
# Extract well formed tables
start = re.compile(r"<table>", re.IGNORECASE)
end = re.compile(r"</table>", re.IGNORECASE)
html_code = ""
table = False
with open('sample2.xml') as xmlfile:
for line in xmlfile:
if not table:
table = start.search(line)
if table:
html_code += line
else:
if end.search(line):
html_code += line[0:end.search(line).end()]
table = False
else:
html_code += line
table = not end.search(line)
print html_code
# Parse html code into Etree Element object
root = ET.fromstring(html_code)
elements = root.findall(".//tr")
print elements
row = []
with open('output.csv', 'wb') as csvfile:
csvwriter = csv.writer(csvfile, delimiter=',', quotechar='"')
for tablerow in elements:
# Only write result to file if there is text inside the first column
if list(tablerow)[0].text:
for col in list(tablerow):
row.append(col.text)
csvwriter.writerow(row)
print row
row = []
如果你打开＆＃34; output.csv＆＃34;使用excel，你将有你的表。如果您使用的是此方法，请注意文档中的安全警告（zezollo评论中的链接）。
或者，您可以使用正则表达式，但我太累了，无法编写其他解决方案。也许明天，或其他人可能会提供替代解决方案。
