Subject: MFC. Extract text from markup

I have the need to get text from a makup control. This control is a preview of some information and it's very fancy to present to user information in a rich way, but I also need to store these information on request... At this point I can of course rebuild all information without markup.. but the better way (for me of course) is to have a command that remove <bold>, <grid> and so on from the full string.

Any hint ?

TIA

Hi,

Here some start:

if (pUIElement)
{
  for (int i = 0; i < pUIElement->GetVisualChildrenCount(); i++)
  {
   CXTPMarkupVisual* pVisual = pUIElement->GetVisualChild(i);

   if (pVisual->IsKindOf(MARKUP_TYPE(CXTPMarkupRun)))
   {
    CXTPMarkupRun* p = (CXTPMarkupRun*)pVisual;
    CString str = p->GetText();
...

}

[ CallRec(pVisual);]

}

so you need call it recursively and find all Runs.

to your markupstatic.cpp code in markup sample I've added this function:

void CMarkupStatic::GetInnerText( CString& sContent, CXTPMarkupVisual* pParent){

ASSERT( pParent);

for (int i = 0; i < pParent->GetVisualChildrenCount(); i++)

{

CXTPMarkupVisual* pVisual = pParent->GetVisualChild( i);

ASSERT( pVisual);

if ( pVisual->IsKindOf(MARKUP_TYPE(CXTPMarkupRun)))

{

CXTPMarkupRun* p = (CXTPMarkupRun*)pVisual;

sContent += p->GetText();

}

GetInnerText( sContent, pVisual);

}

Called as

GetInnerText( sContent, m_pUIElement);

but the resulting string is empty... what's wrong ? can you please help me ?

TIA

Hi,

Here working version. Sorry need Logical Childs:

void CMarkupStatic::GetInnerText( CString& sContent, CXTPMarkupObject* pParent)

{

ASSERT( pParent);

for (int i = 0; i < pParent->GetLogicalChildrenCount(); i++)

{

CXTPMarkupObject* pVisual = pParent->GetLogicalChild(i);

ASSERT( pVisual);

if ( pVisual->IsKindOf(MARKUP_TYPE(CXTPMarkupRun)))

{

CXTPMarkupRun* p = (CXTPMarkupRun*)pVisual;

sContent += p->GetText();

}

GetInnerText( sContent, pVisual);

}

thank you, this code works and with some small enhancements I've added the auto-recognition of TaskPanel end to add a CR+LF to break block of text (and also spaces betwwen block).

What I'm not able to do is insert line feed after a row of a grid, infact using border as marker a line feed is added after each column.

two questions:

1) Any suggestion to detect end of row ?

2) Do you plan o add a more generic and well done function to extract text in future release ?

Thank you agin for your support.
