python-写入html文件可转换特殊字符

Question

I am trying to write into a html file using python, any tags that I add are getting coverted 我正在尝试使用python写入html文件，我添加的所有标签都被隐藏了

eg <tr> to <tr> 例如<tr>到<tr>

Any idea why this is happening and how to avoid it? 知道为什么会这样以及如何避免吗？

In the html page, the exact text that I inserted appears rather than being treated as html tags 在html页面中，我插入的确切文本出现，而不是被视为html标签

Part of the Code: 部分代码：

htmlReport=ElementTree()
htmlReport.parse('result_templte.html')
strTable="<tr><td>Text here</td></tr>"

for node in htmlReport.findall('.//*[@id="table1"]')
    node.text=strTable

htmlReport.write("results.html")

this writes the html tag as < 这会将html标记写为< > into the file. 到文件中。 so the tags inserted are not treated as proper html tags 因此插入的标签不会被视为正确的html标签

You are trying to add an element as a child of another element, but you are actually just adding a plain text string that happens to contain < and > markup delimiters. 您试图将一个元素添加为另一个元素的子元素，但实际上您只是添加了一个纯文本字符串，该字符串恰好包含<和>标记定界符。 To make it work, you need to parse the string to get a new element object and add (append) it in the right place. 要使其工作，您需要解析该字符串以获取一个新的元素对象，并将其添加（附加）到正确的位置。

Let's assume that template.html looks like this: 假设template.html看起来像这样：

<html>

 <table>
 </table>

 <table id="table1">
 </table>

</html>

Then you can add a tr element as a child of the second table as follows: 然后，可以将tr元素添加为第二个table的子元素，如下所示：

from xml.etree import ElementTree as ET

tree = ET.parse('template.html')

# Get the wanted 'table' element
table = tree.find(".//table[@id='table1']")

# Parse string to create a new element
tr = ET.fromstring("<tr><td>Text here</td></tr>")

# Append 'tr' as a child of 'table'
table.append(tr)

tree.write("results.html")

This is what results.html looks like: 这是result.html的样子：

<html>

 <table>
 </table>

 <table id="table1">
 <tr><td>Text here</td></tr></table>

</html>
