XPath 1.0 Query Support

New features:

• Query XML and HTML documents using XPath 1.0 expressions
  • with syntax highlighting and intelligent auto-completion
  • with a custom print function that can be used as a debugging aid by logging nodesets etc. to the console
  • option to display results or select the nodes in the document
  • optionally normalize whitespace when displaying text results (via a setting)
  • with history
  • with support for variables
  • with the node under the first selection/cursor as the context node, and all the nodes under the cursors available in the $contexts variable
• Select entire contents of tag(s) at cursor(s), with or without the open/close tags
• Show XML well-formedness parse errors, with a new entry in the command pallette to move the cursor to the location where the error occurred
• Clean HTML/"tag soup" into valid XML
• option to only show the current xpath in the status bar if the view is not dirty

Compared to the beta4 release, the following changes have been made:

• intelligent auto completion has been added! see the readme for a demonstration
• better syntax highlighting
• some automated tests
• a few tweaks and bug fixes

known bugs:

• auto complete doesn't handle nested functions brilliantly, unless separated by whitespace eg. starts-with(name( would cause issues but starts-with( name( wouldn't. This is due to the way scopes work in ST, specifically finding specific scopes. A fix will be made shortly.
