Unexpected node type Element. The Readelementstring method can only be called on simple content or on empty content

Scenario where the problem occurs:

This error occurs when calling the Ctrip buy interface to deserialize the obtained XML string into the entity object.

Details:

There is such a statement in the XML document "

<description category= "1" title= "description" >
<content title= "description" >
<Text>
Exclusive <b> Hangzhou Zhongshan International Hotel Superior Room </b>1 Night + Free breakfast 2 parts + Free wifi+ more benefits! Hotel is located in the bustling Lakeside shopping district, adjacent to the subway line Line 1 long Xiang Station D exit, walk to the West Lake just 10 minutes, surrounded by shops, traffic is very convenient!
</Text>
</Content>
</Description>

”

Cause of Error:

Because the <Text></Text> tag has a <b></b> tag. <b></b> is not actually an XML node. There are no corresponding fields and attributes in the entity.

Workaround:

Remove the <b></b> tag from this sentence.

Principle Analysis:

The XML contains illegal characters or HTML tags. Workaround please refer to my XML for illegal characters translated into entities article.
