I have a xml like follows,
<doc> <p> first sentence</p> <p>second sentence</p> <p> third sentence</p> </doc>
I need to count the number of spaces (white space) before start the text in
So in above example 2,0,10 should be return.
I can use count() function to get the count and separate the white space string using tokenize() but my problem is write a regular expression to get the needed white space. How can I write a regular expression to get those white spaces?
