Okay, you *might* have a problem. If not, then ignore this, but consider
this email if the ReFindList brings back odd results:
This updated function has a third optional parameter. This third parameter
allows you to change all occurance of a single string with a single
character. This helps searching in regexp sometimes. You won't need to worry
about this unless my first solution does not work:
e.g. ReFindList(documentstring,'<center>(.*?)</center>','</center>') - the
last parameter is temporarily converted to a "§". Any character could be
used provided it does not appear in the document.
Of course, if your <center> tags are nested, you'll be in trouble.
==========================================
function ReFindList(Document,SearchString) {
var ComponentList='';
var thisPosition=1;
var exitloop='false';
if (ArrayLen(Arguments) gte 3) {
if (Arguments[3] neq '') {
Document=ReReplaceNoCase(Document,
Arguments[3], '§', 'ALL');
}
}
while (exitloop eq 'false') {
st=refindnocase(SearchString,Document,thisPosition,'TRUE');
if (st.pos[1] neq 0) {
ComponentList=ListAppend(ComponentList,rereplacenocase(Mid(Document,st.pos[1
],st.len[1]),SearchString,'\1','ALL'));
thisPosition=st.pos[1]+1;
}
else {
exitloop='true';
}
}
if (ArrayLen(Arguments) gte 3) {
if (Arguments[3] neq '') {
ComponentList=ReReplaceNoCase(ComponentList,
'§', Arguments[3], 'ALL');
}
}
return ComponentList;
}
