xml pandas

参照dataframe替换XML中的元素,xml,pandas,lxml,Xml,Pandas,Lxml,我正在使用lxml读取我的xml文件： tree = etree.parse(r'C:\Users\xxx\Desktop\misc work\xmledit\SalesTransactionCustom.xml') 并获取一个xml文件，如： <?xml version="1.0" encoding="UTF-8"?> <ProcessSalesTransactionCustom xmlns="http://schema.xxxx.com/xxxxx/2" releaseI

我正在使用lxml读取我的xml文件：

我想用这个数据框架替换xml中元素的属性。我希望能够找到标记和旧值的组合，并用新值替换属性。我还需要能够将编辑后的文本作为XML写回磁盘

我如何使用lxml和pandas实现这一点

先谢谢你

编辑：这是感谢@Partha Mandal的代码

import pandas as pd
from lxml import etree

df=pd.read_excel("Sample.xlsx")
df.columns=['Tag','Old','New']
df['Old'] = df['Old'].astype(str)
df['New'] = df['New'].astype(str)

parser = etree.XMLParser(remove_blank_text=True)
tree = etree.parse(r'C:\Users\xxx\Desktop\misc work\xmledit\testxml2.xml',parser)
string = etree.tostring(tree)
string = bytes.decode(string)

tag = df.Tag; old = df.Old; new = df.New

for i in range(len(tag)):
   string = string.replace("<"+tag[i]+">"+old[i]+"</"+tag[i]+">","<"+tag[i]+">"+new[i]+"</"+tag[i]+">")

string=str.encode(string)

root = etree.fromstring(string)
my_tree = etree.ElementTree(root)
with open('testxml2.xml', 'wb') as f:
    f.write(etree.tostring(my_tree))

将熊猫作为pd导入
从lxml导入etree
df=pd.read\u excel（“Sample.xlsx”）
df.columns=['Tag'，'Old'，'New']
df['Old']=df['Old'].astype（str）
df['New']=df['New'].astype（str）
parser=etree.XMLParser（删除\u blank\u text=True）
tree=etree.parse（r'C:\Users\xxx\Desktop\misc work\xmledit\testxml2.xml'，解析器）
string=etree.tostring（树）
字符串=字节。解码（字符串）
tag=df.tag；old=df.old；new=df.new
对于范围内的i（len（tag））：
string=string.replace（“+old[i]+”、“+new[i]+”）
string=str.encode（字符串）
root=etree.fromstring（字符串）
my_tree=etree.ElementTree（根）
将open（'testxml2.xml'，'wb'）作为f：
f、 写入（etree.tostring（我的树））

为什么不将

XML

作为字符串读取，然后执行

str.replace

tag = df.Tag; old = df.Old; new = df.New

for i in range(len(tag)):
   _str = _str.replace("<"+tag[i]+">"+old[i]+"</"+tag[i]+">","<"+tag[i]+">"+new[i]+"</"+tag[i]+">")

tag=df.tag；old=df.old；new=df.new
对于范围内的i（len（tag））：
_str=_str.replace（“+old[i]+”，“+new[i]+”）
<代码> > p>因为使用<代码> LXML<代码>，请考虑将专用XML语言转换为不同XML的专用语言，并支持从顶层如Python传递参数。因此，在数据帧记录的循环中集成参数化：
唯一的挑战是将标记的所有唯一值硬编码到XSLT的第二个模板匹配中（管道正常后换行）：
doc:BusinessPartner | doc:LedgerAccount

你可以用它
“|”。join（['doc:'+val表示df['Tag'].unique（）中的val）
“|\n”.join（['doc:'+val代表df['Tag'].unique（）中的val）

XSLT（另存为.xsl，一个特殊的.xml文件）

我添加此代码是为了将其作为字符串读取—“string=etree.tostring（tree）”。然后，我在您的注释中运行for循环，但没有下划线（因为我不确定这是为了什么，也没有定义这样的变量）。因此，我使用'string'而不是'u str'运行for循环，但得到以下错误：TypeError:需要一个类似字节的对象，而不是'str'。在运行str.replace之前，您可以运行string=bytes.decode（string）
？谢谢。我照你说的做了，字符串现在被编辑了。但是，我还需要将其作为XML写回磁盘。（我已经编辑了这个问题）我正在用open（'sample2.xml'，wb'）作为f:string.write（f，encoding=“utf-8”，xml\u declaration=True，pretty\u print=True）尝试代码-，
但是得到的错误是“bytes”对象没有属性“write”。（我再次尝试解码成字符串，但是用'str'而不是'bytes'得到了相同的错误）哦！您是否应该使用f.write…，这可能就是问题所在？
