PythonでBeautifulSoup4を使用してxmlパーサーを作成しようとしています。何らかの理由で、ドキュメントが正しく解析されていません。私のxmlドキュメントを以下に示します。

私が書いたPythonコードを以下に示します。

if __name__ == '__main__':
    soup = BeautifulSoup (
        open('test.xml'),
        'lxml'
    )

    for e in soup.find_all('module',attrs={'name':'Brain Parser'}):
        for i in e.find_all('input'):
            print i.prettify()

そしてこれが結果です：

<input description="0: segmentation sub-cortical structures 1: sulci detection" enabled="true" id="BrainParser_1.Structure" name="Structure" order="0" prefix="-p" prefixallargs="false" prefixspaced="true" required="false"/>

<input description="0: perform segmentation/detection 1: perform training" enabled="true" id="BrainParser_1.Testing" name="Testing" order="1" prefix="-r" prefixallargs="false" prefixspaced="true" required="false"/>

<input description="In testing, it points to the source file in training, it points directory in which the training volumes are saved. " enabled="true" id="BrainParser_1.SourceFile" name="Source File" order="2" required="true"/>

<input description="Directory of trained models." enabled="true" id="BrainParser_1.ModelsDirectory" name="Models Directory" order="4" prefix="-m" prefixallargs="false" prefixspaced="true" required="false"/>

<input description="Only effective in training." enabled="false" id="BrainParser_1.NumberofStructures" name="Number of Structures" order="5" prefix="-n" prefixallargs="false" prefixspaced="true" required="false"/>

<input enabled="false" id="BrainParser_1.NumberofIterations" name="Number of Iterations" order="6" prefix="-t" prefixallargs="false" prefixspaced="true" required="false"/>

<input description="Defalut=0.5, typical 0.0~2.0." enabled="true" id="BrainParser_1.SmoothnessFactor" name="Smoothness Factor" order="7" prefix="-s" prefixallargs="false" prefixspaced="true" required="true"/>

ご覧のとおり、これにinputは子要素がないと考えられますが、そうではありません。少し調べてみたところ、要素は要素の子として解析されているvalueようです。誰かがこれを手伝ってくれる？formatmodule

で呼び出しBeautifulSoupています。"lxml"これは、パーサーを使用しlxmlて入力をHTMLとして解析するように指示します。（HTMLでは、inputタグは自己閉鎖的で子がないため、文字列は有効なHTMLではありません。BeautifulSoupは魔法のHTML修正を行い、inputタグがすぐに閉じることを意味していると判断します。そのため、タグは表示されません。子供。）

で呼び出したい"xml"場合は、入力がXMLドキュメントであることを示します。
