This is my code so far.到目前为止，这是我的代码。
# # Request to get the instrumentID from CDW
listInstrumentID = []
securityPricesCDW = f"https://svc-uat-cdw/cdw/securityPrices/{dateinplay}?limit=10"
r = requests.get(securityPricesCDW).json()
# print(r)
jsonPath = parse("$..'m:assetPricing'[*].'m:pricingSource'[*].'m:instrumentId'[*].'#value'")
for match in jsonPath.find(r):
print(f"match id: {match.value}")
thisdict = match.value
listInstrumentID.append(thisdict)
Anyway, if someone can help me get all the value of Array of Object 'instrumentId' 'm:instrumentId': [{ '#value': '100001380992', '_instrumentIdScheme': 'mhi:MHILIST'无论如何，如果有人可以帮助我获取对象数组的所有值 'instrumentId' 'm:instrumentId': [{ '#value': '100001380992', '_instrumentIdScheme': 'mhi:MHILIST'
Thank you for any suggestions谢谢你的任何建议

Try the below (assuming data is the list of dicts from the post)尝试以下操作（假设data是帖子中的字典列表）
ids = [x['m:assetPricing'][0]['m:instrumentId'][0]['#value'] for x in data]
print(ids)
output输出
['100001380992', '100001380993', '100001380994', '100001380995', '100001380996', '100001380997', '100001380999', '100001381000', '100001381004', '100001381005']

You can try this :你可以试试这个：
from xml.etree import ElementTree
root = ElementTree.parse(url_of_your_file).getroot()
for found in root.findall("m:assetPricing")
print(found.find("m:instrumentId").text)
