现在我想的是，当标签名称是Marks然后检查下一个标签是Marks of Student。如果是，然后提取/打印这两个标签和接下来的3个标签（这将是最小值，最大值和平均值）。我之前建议的更新后的代码是：

import io 
import xml.etree.ElementTree as ET 
import xml.etree.ElementTree 

tree = xml.etree.ElementTree.parse('xmlFile1.xml').getroot() 
parent_map = {c: p for p in tree.getiterator() for c in p} 

def search_data(first_text, next_text): 
    data_with_marks = [data_node 
         for data_node in tree.findall(".//Data") 
         if data_node.text == first_text] 
    for marks_elem in data_with_marks: 
     cell_elem = parent_map[marks_elem] 
     row_elem = parent_map[cell_elem] 
     cell_nodes = list(row_elem) 
     curr_index = cell_nodes.index(cell_elem) 
     next_index = curr_index + 1 
     next_data_node = next(iter(cell_nodes[next_index])) 
     if next_data_node.text == next_text: 
      return [next(iter(cell_node)) 
        for cell_node in cell_nodes[curr_index:curr_index + 6]] 
    return [] 

if __name__ == '__main__': 
    for node in search_data("Marks", "Marks of Student"): 
     print(node.text)

当我运行上面的代码时，没有任何东西会被打印出来。执行0返回代码并没有任何内容显示为打印。这段代码有什么问题？

在线演示是否使用'lxml'？ –

@LaurentLAPORTE我正在使用'xml.etree.ElementTree' – user2966197

首先，你有一个命名空间前缀'ss'，它在你的发布示例中没有声明的地方，因此它不是一个格式良好的XML。上面有''的标签吗？您不能从更大的XML文档中剪切和粘贴。 – Parfait

的if语句元素比较用字符串：

if next(xmlTree.iter()) == 'Marks of Student': 
    ...

尝试：

if next(xmlTree.iter()).text == 'Marks of Student': 
    ...

但是，一个<Data/>元素的下一个元素是<Cell/>元素，而不是下一个<Data/>。

编辑

好了，解决的办法是不容易实现，而不全力支持的XPath和良好的API。最好使用lxml。

但是，这里是一个实现：

首先，我完成你的XML使其可解析：

content = """\ 
<fragment xmlns:ss="foo"> 
<Cell ss:StyleID="s65"><Data ss:Type="String">Variable Name</Data></Cell> 
<Cell ss:StyleID="s65"><Data ss:Type="String">Variable Label</Data></Cell> 
<Cell ss:StyleID="s79"><Data ss:Type="String">Minimum&#10;Value</Data></Cell> 
<Cell ss:StyleID="s79"><Data ss:Type="String">Maximum&#10;Value</Data></Cell> 
<Cell ss:StyleID="s80"><Data ss:Type="String">Mean&#10;Value</Data></Cell> 

<Row ss:AutoFitHeight="0" ss:Height="15"> 
<Cell ss:StyleID="s73"><Data ss:Type="String">Marks</Data></Cell> 
<Cell ss:StyleID="s73"><Data ss:Type="String">Marks of Student</Data></Cell> 
<Cell ss:StyleID="s82"><Data ss:Type="Number">0</Data></Cell> 
<Cell ss:StyleID="s82"><Data ss:Type="Number">96</Data></Cell> 
<Cell ss:StyleID="s83"><Data ss:Type="Number">65.71</Data></Cell> 
</Row> 
<Row ss:AutoFitHeight="0" ss:Height="15"> 
<Cell ss:StyleID="s73"><Data ss:Type="String">Name</Data></Cell> 
<Cell ss:StyleID="s73"><Data ss:Type="String">Name of Students</Data></Cell> 
<Cell ss:StyleID="s82"><Data ss:Type="Number">n/a</Data></Cell> 
<Cell ss:StyleID="s82"><Data ss:Type="Number">n/a</Data></Cell> 
<Cell ss:StyleID="s83"><Data ss:Type="Number">n/a</Data></Cell> 
</Row> 
</fragment> 
"""

我解析字符串的内容是这样的：

import io 
import xml.etree.ElementTree as ET 

istream = io.StringIO(content) 
tree = ET.parse(istream)

这里有亲子关系的诀窍：

parent_map = {c: p for p in tree.getiterator() for c in p}

连续两个数据，第一个文本是first_text和下一个文本中第一次出现下面的函数搜索next_text：

def search_data(first_text, next_text): 
    data_with_marks = [data_node 
         for data_node in tree.findall("//Data") 
         if data_node.text == first_text] 
    for marks_elem in data_with_marks: 
     cell_elem = parent_map[marks_elem] 
     row_elem = parent_map[cell_elem] 
     cell_nodes = list(row_elem) 
     curr_index = cell_nodes.index(cell_elem) 
     next_index = curr_index + 1 
     next_data_node = next(iter(cell_nodes[next_index])) 
     if next_data_node.text == next_text: 
      return [next(iter(cell_node)) 
        for cell_node in cell_nodes[curr_index:curr_index + 6]] 
    return []

您可以使用此功能是这样的：

for node in search_data("Marks", "Marks of Student"): 
    print(node.text)

您得到：

Marks 
Marks of Student 
0 
96 
65.71

：

for node in search_data("Name", "Name of Students"): 
    print(node.text)

你得到：

Name 
Name of Students 
n/a 
n/a 
n/a

我试过'if next（xmlTree.iter（））。text =='Age of Patient'：print（'Yes'）'但仍然没有输出 – user2966197

此外，如果问题是因为下一个元素是''而不是''那么我怎样才能匹配''的值？ – user2966197

我试过更新代码，但我仍然没有打印出任何东西。我已更新我的帖子以反映当前代码 – user2966197
