Hello, Daniel -- first of all, thanks so much for implementing the xpointer() scheme -- I can try it out at last :-)
There is a problem that I get under both libxml 2.6.32 and 2.7.2, illustrated by the following, which is a test case for extracting substrings for the purpose of text annotation: include2.xml <?xml version="1.0" encoding="UTF-8"?> <body><p><xi:include xmlns:xi="http://www.w3.org/2003/XInclude"; href="source.xml" xpointer="xpointer(string-range(/div,'',1,47)[1])"/></p> <p><xi:include xmlns:xi="http://www.w3.org/2003/XInclude"; href="source.xml" xpointer="xpointer(string-range(/div,'',50,22)[1])"/></p> <p><xi:include xmlns:xi="http://www.w3.org/2003/XInclude"; href="source.xml" xpointer="xpointer(string-range(/div,'',73,11)[1])"/></p></body> source.xml <?xml version="1.0" encoding="UTF-8"?> <div><p>To make a prairie it takes a clover and one bee, One clover, and a bee, And revery. The revery alone will do, If bees are few</p></div> ----------- $ xmllint --xinclude --debug include2.xml Internal error at /usr/src/ports/libs/libxml2/libxml2-2.6.32-2/src/libxml2-2.6.32/xpointer.c:2409 Internal error at /usr/src/ports/libs/libxml2/libxml2-2.6.32-2/src/libxml2-2.6.32/xpointer.c:2409 DOCUMENT version=1.0 encoding=UTF-8 URL=include2.xml standalone=true ELEMENT body ELEMENT p INCLUDE START TEXT content=To make a prairie it takes a clover and ... INCLUDE END TEXT compact content= ELEMENT p INCLUDE START TEXT content=One clover, and a bee, INCLUDE END TEXT compact content= ELEMENT p INCLUDE START TEXT content=And revery. INCLUDE END The error goes away in two cases: when I comment out the two latter <p>s, or when I put a designated character at the the very beginning of the source.xml text, and match against it, e.g.: <p><xi:include xmlns:xi="http://www.w3.org/2003/XInclude"; href="source.xml" xpointer="xpointer(string-range(/div,' ',3,48)[1])"/></p> The error context in xpointer.c is in xmlXPtrAdvanceChar(): if (pos > len) { /* Strange, the indx in the text node is greater than it's len */ STRANGE pos = len; } And I can't see what I possibly do wrong here. Thought I'd let you know, in case the problem was xmllint's. The relevant fragment of the xpointer draft is at http://www.w3.org/TR/xptr-xpointer/#stringrange Best regards, Piotr _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] http://mail.gnome.org/mailman/listinfo/xml
