Having an extra <ul> tag throws an error "System.InvalidOperationException: Sequence contains no elements"

Report issue

If there is an extra <ul> in the html string, the package throws the below error
System.InvalidOperationException: Sequence contains no elements
at System.Linq.ThrowHelper.ThrowNoElementsException()
at System.Linq.Enumerable.Aggregate[TSource](IEnumerable1 source, Func3 func)
at Html2Markdown.Replacement.HtmlParser.ReplaceList(String html)
at Html2Markdown.Replacement.HtmlParser.ReplaceLists(String html)
at Html2Markdown.Replacement.CustomReplacer.Replace(String html)
at Html2Markdown.Converter.<>c.b__5_0(String current, IReplacer element)
at System.Linq.Enumerable.Aggregate[TSource,TAccumulate](IEnumerable1 source, TAccumulate seed, Func3 func)
at Html2Markdown.Converter.Convert(String html)

The String used to test this -
<ul><ul><li>first list val</li></ul></ul>

Expected behavior

The extra <ul> tag should be ignored.

Actual Behaviour

Error

Steps to reproduce the problem

var description = "<ul><ul><li>first list val</li></ul></ul>"; var converter = new Converter(); markdown = converter.Convert(description);

@shettyanusha thanks for raising the bug. Are you using the latest version of the package? If I try and use your reproduction case I get an empty string. That is obviously still a bug but not this error.

@shettyanusha - I am in the midst of releasing this to Nuget. It wil be in version 6.2.1.4.

Kind regards.

Thank you so much @baynezy. I'm on .NETStandard 2.1 and it seems like version 6 is not compatible with it. The Html2Markdown version is 5.1.0
