pywinauto print_control_identifier显示该元素，但无法通过ElementNotFoundError获取它

如何解决pywinauto print_control_identifier显示该元素，但无法通过ElementNotFoundError获取它

我试图使用child_window（）函数在父节点下获取元素，但未找到错误。 这是父项的print_control_identifier（）输出：

db.getCollection('urls').aggregate([
    {
        // creating a nested array with keys and values
        // of the payload subdocument.
        // all other fields of the original document
        // are removed and only the filed arrayofkeyvalue persists
        "$project": {
            "arrayofkeyvalue": {
                "$objectToArray": "$$ROOT.payload"
            }
        }
    },{
        "$project": {
            // extract only the keys of the array
            "urlKeys": "$arrayofkeyvalue.k"
        }
    },{
        // merge all documents
        "$group": {
            // _id is mandatory and can be set
            // in our case to any value
            "_id": 1,// create one big (unfortunately double
            // nested) array with the keys
            "urls": {
                "$push": "$urlKeys"
            }
        }
    },{
        // "explode" the array and create
        // one document for each entry
        "$unwind": "$urls"
    },{
        // "explode" again as the arry
        // is nested twice ...
        "$unwind": "$urls"
    },{
        // Now "query" the documents
        // with your regex
        "$match": {
            "urls": {
                "$regex": /url_/
            }
        }
    },{
      // finally count the number of
      // matched documents
        "$count": "count"
    }
])

我运行了以下代码，尝试在编辑控件中更改文本并出现错误：

>>> txb_custom.print_control_identifiers()
Control Identifiers:

Custom - ''    (L997,T127,R1075,B177)
['PET WBCustom','Custom']
child_window(auto_id="textBox",control_type="Custom")
   | 
   | Edit - 'PET WB'    (L997,B177)
   | ['Edit','PET Wbedit']
   | child_window(title="PET WB",auto_id="textBox",control_type="Edit")
   |    | 
   |    | ScrollBar - ''    (L0,T0,R0,B0)
   |    | ['ScrollBar','ScrollBar0','ScrollBar1']
   |    | child_window(auto_id="VerticalScrollBar",control_type="ScrollBar")
   |    | 
   |    | ScrollBar - ''    (L0,B0)
   |    | ['ScrollBar2']
   |    | child_window(auto_id="HorizontalScrollBar",control_type="ScrollBar")
