我在下面复制了一个名为“dictionary.xml”的 XML 文档。由于某种原因，该文档无法被 python 中的 XmlToDict 解析。
<dictmap>
<lexelt item="begin.v" num="4">
<sense id="1" wordnet="2,3,5,6,7" gloss="start, have an initial point " examples="Prices for these homes begin at $250,000 | The war began on a Thursday. | She began to feel sick. | When life began was there oxygen in the atmosphere? | The novel begins with a shipwreck at sea. | It's beginning to look like rain. | His property begins at the fence." />
<sense id="2" wordnet="1,8,5" gloss="initiate an undertaking" examples="They'll begin their tour with a concert in London. | You should begin the stew now so it will have four hours to simmer. | The government is beginning to protect the coral reefs of that island. | He was just beginning a novel when the phone rang. | Acme Tire Co. began offering their employees health insurance. | John has begun to take them seriously. | She began ballet at age four." />

</lexelt>
<lexelt item="complain.v" num="2">

<sense id="2" wordnet="2" gloss="make formal, legal accusation or bring charge" examples="The neighbors complained to the police about the noise. | We have complained to the authorities and they will need to take action now. | The lawyer complained that the defendant had physically abused his client." />
</lexelt>
</dictmap>
以下代码应该可以工作，但会触发以下错误：
xmltodict.parse('dictionary.xml')
>>>>

我需要做什么来纠正这个问题？
