the line containing the next occurrence of "OPENBABEL_INSERT".
\param pos is updated to the start of the next line.
If "OPENBABEL_INSERT" is not found, and \param ToInsertOnly is false
the text up to the end of the file is returned and \param pos is set to 0.
If "OPENBABEL_INSERT" is not found, and \param ToInsertOnly is true
an empty string is return and \param pos is unchaged.
Inserting OpenBabel output into boilerplate text.
Suppose you wanted to insert XML output from OB into into a template XML document
using the babel interface
babel template.text inputfile.xxx outputfile.yyy
The template file could contain a line:
<!-- OPENBABEL_INSERT here -->
and still be well-formed XML.
The template file would be read by TextFormat and passed to the output as an OBText object.
This could be processed in the output format's WriteChemObject() or WriteMolecule()
in the following way (see cmlreactformat.cpp)
<code>
OBText* ptext = dynamic_cast<OBText*>(pOb);
if(ptext) {
string::size_type pos = 0;
*pConv->GetOutStream() << ptext->GetText(pos); //Output text up to insertion point
_text = ptext->GetText(pos); //Save text after insertion point to be output at the end
}
</code>

{
std::string::size_type oldpos = pos;
std::string::size_type newpos = txt.find("OPENBABEL_INSERT", pos);
if(newpos== std::string::npos)//not found: return rest of txt
{
if(ToInsertOnly)
return("");
pos = 0;
return txt.substr(oldpos);
}
newpos = txt.rfind('\n', newpos); //to end of previous line
pos = txt.find("\n", newpos+1)+1; //to past end of line, or 0
return txt.substr(oldpos, newpos-oldpos);
}
