Document visible content

Hi support,

I’m trying to find a way to check if my document has any visible content in its body. For example, I search within the paragraphs collection for text, if there is any non-empty content within the text’s segments. But it works if I have only texts elements in the document : the cast from PdfElementBase to Text works. But I might have tables, or any other type of elements, and I cannot cast, because I do not know the type of the PdfElementBase.

Here is a sample :

for(int i = 0; i < firstSection.getParagraphs().size(); ++i)
{
PdfElementBase element = firstSection.getParagraphs().get(i);
Text text = (Text) element;
if(text != null)
{
for(int x = 0; x < text.getSegments().size(); ++x)
{
Segment seg = text.getSegments().getAt(x);
if(!seg.getContent().isEmpty())
{
textHasContent = true;
break;
}
}
if(textHasContent)
{
break;
}
}
}

Please advice,
Milan

Hi support,

I’ve found that section.getParagraphs().get(index).getDOMElement().getNodeName() returns the type of that paragraph : “Table”, “Text” etc. Is there any other solution ?

Hi Milan,

Sorry for replying to you so late because of the holiday in China. I think the getNodeName()can help you to check the visible content. We have not found other solution.
