使用 python 脚本生成 xml 文件时出现缩进错误

Question

我试图通过读取 excel sheet 使用 python 脚本创建 XML 文件。使用 yattag 我可以做到这一点，尽管我需要的格式并不完全是这样。我粘贴了下面的代码并且已经验证没有混合 spaces/tabs.

目标是将整个项目包装在 'node' 标签中，并为两个 'category' 标签添加 2 个子类别。我收到错误是因为在 'node' 标签之后我在 'location' 标签之前有 2 个标签。如果我修复错误，我会得到第一组代码。如果有意义的话，基本上只需要将'

<node type="document" action="create">
        <location>TempCD</location>
        <title>doc1</title>
        <file>E:\Doc1.docx</file>
        <mime>application</mime>
    </node>
    <category name="Content">
        <attribute name="Function">asd</attribute>
        <attribute name="Commodity">sf</attribute>
        <attribute name="Sub-Commodity">qw</attribute>
        <attribute name="Contract/Document Owner">e</attribute>
        <subitems>reapply</subitems>
    </category>
    <category name="Content Server Categories:LYB:LYB-GSC-Contracts">
        <attribute name="Supplier">Altom Transport</attribute>
        <attribute name="Pricing Terms">Fixed</attribute>
        <attribute name="Term Type">Fixed</attribute>
        <subitems name="Commodity">reapply</subitems>
    </category>

这应该会给您 xml 您正在寻找的：

from openpyxl import load_workbook
from yattag import Doc, indent

wb = load_workbook("input_sample.xlsx")
ws = wb.worksheets[0]

# Create Yattag doc, tag and text objects
doc, tag, text = Doc().tagtext()

xml_header = '<?xml version="1.0" encoding="UTF-8"?>'
xml_schema = '<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"></xs:schema>'

doc.asis(xml_header)
#doc.asis(xml_schema)  # invalid

with tag('root'):  # required for valid xml
    for row in ws.iter_rows(min_row=2):
        row = [cell.value for cell in row]
        with tag('node', type=row[0], action=row[1]):
                with tag("location"): text(row[2])
                with tag("title"): text(row[3])
                with tag("file"): text(row[4])
                with tag("mime"): text(row[5])
                with tag('category', name=row[6]):
                    with tag("attribute", name='Function'): text(row[7])
                    with tag("attribute", name='Commodity'): text(row[8])
                    with tag("attribute", name='Sub-Commodity'): text(row[9])
                    with tag("attribute", name='Contract/Document Owner'): text(row[10])
                    with tag("subitems"): text("reapply")
                with tag('category', name=row[11]):
                    with tag("attribute", name='Supplier'): text(row[12])
                    with tag("attribute", name='Pricing Terms'): text(row[13])
                    with tag("attribute", name='Term Type'): text(row[14])
                    with tag("subitems"): text("reapply")
                

result = indent(
doc.getvalue(),
indentation = '    ',
indent_text = False
)

with open("test_resulted.xml", "w") as f:
   f.write(result)

输出

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <node type="2" action="2">
        <location>2</location>
        <title>2</title>
        <file>2</file>
        <mime>2</mime>
        <category name="2">
            <attribute name="Function">2</attribute>
            <attribute name="Commodity">2</attribute>
            <attribute name="Sub-Commodity">2</attribute>
            <attribute name="Contract/Document Owner">2</attribute>
            <subitems>reapply</subitems>
        </category>
        <category name="2">
            <attribute name="Supplier">2</attribute>
            <attribute name="Pricing Terms">2</attribute>
            <attribute name="Term Type">2</attribute>
            <subitems>reapply</subitems>
        </category>
    </node>
    <node>
       ..........
    </node>
    ..............
</root>
