Getting text of a Node throws InvalidOperationException using C#

Aspose.Words Product Family
1

Hi,

I changed version from Aspose.Words 9.5 to Aspose.Words 11.0
I use the same code that worked fine in 9.5 , but in 11.0 it is raising the exception:
"System.Message: System.InvalidOperationException: Stack Empty "…

The line that causes the exception looks like that :
Aspose.Words.NodeCollection runNodes = GetChildNodes();
for(i=o;i< runNodes.Count;i++)
{
string curText = runNodes[i].ToTxt();
}

when I use the .ToTxt() Method on vaild node I get wothout reason the “Stack Empty” Exception ,

Why does it happens and how can I solve this problem (Do you have a patch or new dll for it ? )

Help us urgently,

Thank you,

Hi Itay,

Thanks for your query. It would be great, If you share your document for investigation purposes and also share code for GetChildNodes() method.

Meanwhile the code is on another machine that I cant copy ...
GetChildNodes() implementation:
return (currPar as Aspose.Words.Paragraph).GetChildNodes(NodeType.Run, true );


The purpose is to run on found paragraph by linq and then insert hyperlinks on requested nodes matching our conditions,

Is it enough for you to understand the problem or explain to me what can cause it , as I said it worked fine on version 9.5?

TNX

Hi there,


Thanks for your inquiry.

We are aware of this issue. Your request has been linked to the appropriate issue. We will inform you as soon as it is resolved.

In the mean time you can work around this issue by casting each node to a run and then using the run.Text property instead.

Thanks,
