The client must inform the parser what objects to stream back via an xpath expression. Consider the following example. <pre> <code> Configuration config = ... //some configuration String input = ... //some instance document String xpath = "//envelope"; StreamingParser parser = new StreamingParser(config,input,xpath); Envelope e = null; while((e = (Envelope)parser.parse()) != null) { //do something } </code> </pre> The xpath expression <code>//envelope</code> matches any element named <code>envelope</code> in the instance document. Whenever the parser has turned such an element into an object (an instance of Envelope), the object is returned. </p><P><P><DL><DT><B>Author:</B></DT> <DD>Justin Deoliveira, The Open Planning Project</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/geotools/xml/StreamingParser.html#StreamingParser(org.geotools.xml.Configuration, java.io.InputStream, java.lang.String)">StreamingParser</A></B>(<A HREF="../../../org/geotools/xml/Configuration.html" title="interface in org.geotools.xml">Configuration</A> configuration, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/io/InputStream.html" title="class or interface in java.io">InputStream</A> input, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> xpath)</CODE><BR> Creates a new instance of the streaming parser.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../org/geotools/xml/StreamingParser.html#StreamingParser(org.geotools.xml.Configuration, java.lang.String, java.lang.String)">StreamingParser</A></B>(<A HREF="../../../org/geotools/xml/Configuration.html" title="interface in org.geotools.xml">Configuration</A> configuration, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> input, <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> xpath)</CODE><BR> Creates a new instance of the streaming parser.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== -->⌨️ 快捷键说明
