XML переупорядочивает атрибуты порядка python

Question

Мне нужно, чтобы мои пары значений атрибутов XML были переставлены в определенном порядке. Это потому, что я запускаю сторонний инструмент для обработки этих файлов, и он ищет атрибуты в определенном порядке.

Я хотел бы иметь список, в котором подробно указан порядок, который я указываю

Я искал, но не смог найти ничего, что делает то, что я хочу.

order = ["attrib1","attrib2","attrib3",.........]

XML до:

<signal id = "signal1"
atrib6 = "value6"
atrib5 = "value5"
atrib4 = "value4"
atrib3 = "value3"
atrib2 = "value2"
atrib1 = "value1"/>
<signal id = "signal2"
atrib1 = "value1"
atrib7 = "value7"
atrib2 = "value2"
atrib4 = "value4"
atrib8 = "value8"
atrib15 = "value15"/>
<signal id = "signal3"
atrib10 = "value10"
atrib17 = "value17"
atrib3 = "value3"
atrib1 = "value1"
atrib6 = "value6"
atrib22 = "value22"/>

XML после

<signal id = "signal1"
atrib1 = "value1"
atrib2 = "value2"
atrib3 = "value3"
atrib4 = "value4"
atrib5 = "value5"
atrib6 = "value6"/>
<signal id = "signal2"
atrib1 = "value1"
atrib2 = "value2"
atrib4 = "value4"
atrib7 = "value7"
atrib8 = "value8"
atrib15 = "value15"/>
<signal id = "signal3"
atrib1 = "value1"
atrib3 = "value3"
atrib6 = "value6"
atrib10 = "value10"
atrib17 = "value17"
atrib22 = "value22"/>

Мне известно, что в спецификации XML сказано, что порядок атрибутов не важен. Однако сторонний программный инструмент не будет работать, если атрибуты не находятся в определенном порядке.

Answer 1

Хорошо, вот мое решение: мой входной файл "input.xml" выглядит так:

<element-name attrib_7="value7" attrib_6="value6" attrib_5="value5" attrib_4="value4" attrib_3="value3" attrib_2="value2" attrib_1="value1" />
<element-name attrib_5="value5" attrib_4="value4" attrib_3="value3" attrib_1="value1" attrib_2="value2" attrib_6="value6" attrib_2="value2" />
<element-name attrib_6="value6" attrib_4="value4" attrib_2="value2" attrib_1="value1" />

в выходной файл "output.xml":

<element-name
attrib_1="value1"
attrib_2="value2"
attrib_3="value3"
attrib_4="value4"
attrib_5="value5"
attrib_6="value6"
attrib_7="value7"
/>
<element-name
attrib_1="value1"
attrib_2="value2"
attrib_3="value3"
attrib_4="value4"
attrib_5="value5"
attrib_6="value6"
/>
<element-name
attrib_1="value1"
attrib_2="value2"
attrib_4="value4"
attrib_6="value6"
/>

    if "<element-name" in line and "/>" in line:

        a,b,c,d,e,f,g,h,i = "","","","","","","","",""
        sortedattribs = []

        xmlsorted.append(sortedattribs)
        outfile.writelines(sortedattribs)

infile.close()
outfile.close()
