嘗試解析 XML BLOB 并將其轉(zhuǎn)換為 CSV。使用本地文件時(shí)可以使用以下代碼。import xml.etree.ElementTree as etSourceFileName = req.params.get('FileName')SourceContainer = "C:\\AzureInputFiles\\"SourceFileFullPath = SourceContainer + SourceFileNamextree = et.parse(SourceFileFullPath)xroot = xtree.findall(".//data/record") df_cols=['Col1', 'Col2']rows = []在 Azure BLOB 上工作時(shí)無法使用。我怎樣才能做到這一點(diǎn) ？不是最干凈的，但通過創(chuàng)建帶參數(shù)的 URL 嘗試了以下方式。容器設(shè)置為公共訪問，Blob 沒有限制。使用的庫：azure-storage-blobimport xml.etree.ElementTree as eturl = f"https://{account_name}.blob.core.windows.net/{container_name}/{blob_name}"xtree = et.parse(url)xroot = xtree.findall(".//data/record") df_cols=['Col1', 'Col2']rows = []有什么建議可以讓它發(fā)揮作用嗎？訪問 Blob 的更好方法？

如果你想從 Azure blob 中讀取 xml 文件，我們可以使用 packageazure.storage.blob來實(shí)現(xiàn)它。
例如
我的 xml 文件
<?xml version="1.0"?>
<data>
<country name="Liechtenstein">
<rank>1</rank>
<year>2008</year>
<gdppc>141100</gdppc>
<neighbor name="Austria" direction="E"/>
<neighbor name="Switzerland" direction="W"/>
</country>
<country name="Singapore">
<rank>4</rank>
<year>2011</year>
<gdppc>59900</gdppc>
<neighbor name="Malaysia" direction="N"/>
</country>
<country name="Panama">
<rank>68</rank>
<year>2011</year>
<gdppc>13600</gdppc>
<neighbor name="Costa Rica" direction="W"/>
<neighbor name="Colombia" direction="E"/>
</country>
</data>
代碼
import xml.etree.ElementTree as ET
from azure.storage.blob import BlobServiceClient
connection_string='<your storage account connection string>'
blob_service_client = BlobServiceClient.from_connection_string(connection_string)
blob_client = blob_service_client.get_blob_client(container="test", blob="data.xml")
downloader = blob_client.download_blob()
root = ET.fromstring(downloader.content_as_text())
for neighbor in root.iter('neighbor'):
print(neighbor.attrib)
