Question

我有一个xml树作为字符串。我想将这棵树插入beautifulsoup对象内的另一个标签中。

我想在标签stra内插入字符串<voucher action="Create" objview="Accounting Voucher View" vchtype="Journal">。

在原始文件中，凭证标签内没有任何内容。

代码：

from bs4 import BeautifulSoup as bs

stra = r'''<DATE>20190101</DATE>
      <VOUCHERTYPENAME>Journal</VOUCHERTYPENAME>
      <VOUCHERNUMBER>5</VOUCHERNUMBER>
      <PERSISTEDVIEW>Accounting Voucher View</PERSISTEDVIEW>
      <EFFECTIVEDATE>20190101</EFFECTIVEDATE>    
      <MASTERID> 1</MASTERID>

      <ALLLEDGERENTRIES.LIST>
       <LEDGERNAME>Salary Payable</LEDGERNAME>
       <ISDEEMEDPOSITIVE>No</ISDEEMEDPOSITIVE>
       <AMOUNT>1000.00</AMOUNT>
       <VATEXPAMOUNT>1000.00</VATEXPAMOUNT>
      </ALLLEDGERENTRIES.LIST>'''
newsoup=bs(stra)

f = open(r"F:\Users\Administrator\Desktop\TallyJVXml.txt").read()
soup = bs(f,'lxml')
l = soup.find("voucher".lower())
l.append(stra)
print(soup)

当前输出：

版本2-保留大写XML字符串（data1，data2与前面的相同）：

from bs4 import BeautifulSoup

soup1 = BeautifulSoup(data1, 'xml')
soup2 = BeautifulSoup('<HELPERTAG>' + data2 + '</HELPERTAG>', 'xml')
body = soup2.select_one('HELPERTAG')
soup1.select_one('VOUCHER[VCHTYPE="Journal"]').append(body)
body.unwrap()

print(soup1.prettify())
