Hi to all.
I've the following feature request. It is not an 'official' feature request, since I do not know if there is some functionality in Eclipse or in some 3rd party plugin that offers this feature. Just an attempt to discuss an idea for a new XML plugin.

The feature I'm looking for is a search page analogous to the normal textual search page. The purpose is to look into xml documents in a certain scope (workspace, resource and children, working set) for text and structure (for example using XPath).
The reason behind this is that plugins I found work only on one resource at a time, while I'd like to search in the wole context. Textual search is what I'm using now, but sometimes I need to do searches like:

tell me what docs have tag X with prop a=10 and prob b=20. The problem is that matching
<X a="10" .... b="20">
<X a="10" .... b="20"/>
<X .... a="10" b="20">
<X .... a="10" b="20" ....>
<X a="10" b="20" ....>
<X b="20" a="10">

is rather easy for an XML lib but rather difficult to do with regular expressions.

I'd also love to have this both as UI and as core API do use it in custom XML plugin like mine (it is a 'normal' StructuredTextViewerConfigurationXML extension)

what do you think about?

thanks
Alex

We could do this pretty easily using PsychoPath XPath 2.0 processor within eclipse so that it gathers all the XML content-type files and does a collection()/x[@a=10 and @b=10]

With the XPath View we might be able to also create some functionality so that you can specify a collection as an input if using the XPath 2.0 processor.

Please open a enhancement request and we can look at adding this during the WTP 3.3 release time frame. You'll want open this against the wst.xsl component in WTP Source Editing as that is where the XPath functionality is maintained. If you install the XSL Tools editor and debugger you'll get the XPath view.
