.IX Title "SVG::DOM 3"
.TH SVG::DOM 3 "2003-11-02" "perl v5.8.0" "User Contributed Perl Documentation"
.SH "NAME"
SVG::DOM \- A library of DOM (Document Object Model) methods for SVG objects.
.SH "SUMMARY"
.IX Header "SUMMARY"
\&\s-1SVG::DOM\s0 provides a selection of methods for accessing and manipulating \s-1SVG\s0
elements through DOM-like methods such as getElements, getChildren, getNextSibling
and so on. 
.PP
Currently only methods that provide read operations are supported. Methods to
manipulate \s-1SVG\s0 elements will be added in a future release.
