gdb hint for debugging libxml
From a letter to the libxml mailing list. Probably it's well known, but I'd like to share useful gdb settings. From my ~/.gdbinit:
<code> define xp call xmlDebugDumpNode(stdout, $arg0, 0) end document xp Executes xmlDebugDumpNode(stdout, arg, 0). Use also: xmlDebugDumpOneNode xmlDebugDumpNodeList xmlDebugDumpDocument end </code>
Now, debugging in gdb, it's possible to dump a variable as an XML node:
<screen> (gdb) cont Breakpoint 2, xmlFreeNode (cur=0x8051760) at tree.c:3333 3333 xmlDictPtr dict = NULL; (gdb) help xp Executes xmlDebugDumpNode(stdout, arg, 0). Use also: xmlDebugDumpOneNode xmlDebugDumpNodeList xmlDebugDumpDocument (gdb) xp cur TEXT content= test.xsl:0: error : Node has no parent </screen>
