解析：字符串到XML [英] Parsing : String to XML

问题描述

我的API应该采用字符串并将其类型转换为XML格式。

my API is supposed to take a string and typecast it to XML format.

但是我一直在遇到此错误：

But i am consistently getting this error :

ParseError：不匹配的标记：第1行，第764行

ParseError: mismatched tag: line 1, column 764

XML

<?xml version="1.0" encoding="utf-8" ?>
<MasterDetails IssuerId="5" Version="12.2">
    <XMLRequest />
    <BookingDetails  Amount="768"  Comment="Hotel Travel Purchase"  CurrencyCode="INR"  PurchaseType="Hotel"  SupplierName="SomeHotel"  CardAlias="C_ALIAS"  ValidFor="-1D"  CurrencyType="B" />
    <CDFs>
        <CDF FieldName="Order Date" FieldValue="2015-01-01" />
    </CDFs>
    <SomeTag>
        <Rule Action="A" Alias="MyAlias">
            <Controls>
                <OPMCCControl Negate="False"/>
                <OPMIDControl />
                <SomeControlsTags       CumulativeLimit="768"       MaxTrans="None"                 Period="C" />
                <ValidityPeriod           ValidFrom="2015-01-01 00:00:00.0 +0000"          ValidTo="2015-01-11 00:00:00.0 +0000" />
            </Controls>
        </Rule>
    </SomeTag>
</BookingDetails>
<Email  EmailAddress="[e-mail]"/>
<MasterDetails />

通过以下方式实现：

tree = ET.ElementTree(ET.fromstring(kk.strip()))

我确定我的XML字符串包含所有匹配的标签并且已格式化，但是仍然有些东西在我眼前！

I know for sure that my XML string is containing all matching tags and is formatted but still something might be missing infront of my eyes!!

推荐答案

BookingDetails 标记在此行上自动关闭：

The BookingDetails tag is self-closed on this line:

<BookingDetails  Amount="768"  Comment="Hotel Travel Purchase"  CurrencyCode="INR"  PurchaseType="Hotel"  SupplierName="SomeHotel"  CardAlias="C_ALIAS"  ValidFor="-1D"  CurrencyType="B" />

但是当有单独的结帐 BookingDetails 元素：

But when there is a separate closing BookingDetails element:

</BookingDetails>

此外，< MasterDetails /> 在最后一行没有正确关闭。应该是< / MasterDetails> 而不是< MasterDetails /> 。

Also, the <MasterDetails /> is not properly closed on the last line. Should be </MasterDetails> instead of <MasterDetails />.

请注意，您可以在 lxml.etree ，则为 nofollow>恢复模式：

Note that you can parse this XML in the "recover" mode if lxml.etree is used:

import lxml.etree as ET

parser = ET.XMLParser(recover=True)
tree = ET.ElementTree(ET.fromstring(data, parser=parser)) 

或者，使用 BeautifulSoup 具有 xml 功能：

from bs4 import BeautifulSoup

soup = BeautifulSoup(data, "xml")
print(soup.prettify())
