我似乎无法删除其值包含某个字符串的字典的键，为什么？

Question

我有这段代码，它获取一个XML文件，并获取text标签的子元素（new_line标签），并将其索引存储为字典中的键，并将这些元素存储为同一字典中的值。我想删除其值包含“ 10.238”的字典的键，但是它似乎不起作用。其他一切正常。这是我的代码：

import re
from xml.dom import minidom
from xml.etree import ElementTree as ET


def filter_values_by_keyword(my_dict, filter_by):
    """
    Return a list of values which contains `filter_by` keyword.

    Arguments:
        my_dict (dict): Dict containing (...data specifics here)
        filter_by (str): Keyword to look for in values of my_dict

    Return:
        List of filtered values
    """
    return [key for key, value in my_dict.items() if filter_by in value]


def get_xml_by_tag_names(xml_path, tag_name_1, tag_name_2):
    """
    Your docstring here.
    """
    data = {}
    xml_tree = minidom.parse(xml_path)
    item_group_nodes = xml_tree.getElementsByTagName(tag_name_1)
    for idx, item_group_node in enumerate(item_group_nodes):
        cl_compile_nodes = item_group_node.getElementsByTagName(tag_name_2)
        for _ in cl_compile_nodes:
            data[idx]=[item_group_node.toxml()]
    return data


def main():
    data = get_xml_by_tag_names('output2.xml', 'new_line', 'text')
    filtered_values = filter_values_by_keyword(data, '10.238')

    for item in filtered_values:
        del data[item]

    for value in data.values():
        myxml = ' '.join(value)
        # print(myxml)

        tree = ET.fromstring(myxml)
        lista = ([text.text for text in tree.findall('text')])
        testo = (' '.join(lista))

        print(testo)


if __name__ == "__main__":
    main()

这是XML的示例：

Answer 1

给您另一个可以帮助您的示例。

from simplified_scrapy import SimplifiedDoc,req,utils
html = '''
Your xml
'''
doc = SimplifiedDoc(html)
# texts = doc.getElements('text').notContains('-',attr='text').text # Filter with text
texts = doc.getElements('text').notContains('10.238',attr='size').text # Filter with size
print(texts)

结果：

['della quale non conosce che una parte;]', 'prima', '1', 'che nonconosce ancora appieno;', '2', 'che', 'viso] vi', 'su', 'm']
