Maybe someone can help, is it a way to combine an xPath expression to query node by it's property value?
I have a node with custom property "ItemId". I need something like this:
uQuery.GetNodesByXPath("//* [#itemId = '<someId>']")
Thanx in advance!
"//*" Will give you all nodes, so "//*[#itemId = '<someId>']" is asking to give you all nodes with an attribute equal to exactly "<someId>", which you can't have as a valid attribute.
So, if you have <myNode someId='my Id value'></myNode> , then try //*[#itemId='someId']
But remember, this will give you ANY node with that particular attribute ID.
I'm not sure if this is what you're looking for, but please post your XML or a snippet of what you're grabbing, as that will clear up any grey areas.

I have the following XML:
<envelope>
<action>INSERT</action>
<auditId>123</auditId>
<payload class="vendor">
<fizz buzz="3"/>
</payload>
</envelope>
I am trying to write an XPath expression that will pluck out vendor (value for the payload's class attribute) or whatever its value is.
My best attempts are:
/dataEnvelope/payload[#class="vendor"]#class
But this requires the expression to already know that vendor is the value of the attribute. But if the XML is:
<dataEnvelope>
<action>INSERT</action>
<auditId>123</auditId>
<payload class="foobar">
<fizz buzz="3"/>
</payload>
</dataEnvelope>
Then I want the expression to pluck out the foobar. Any ideas where I'm going awry?
If you need #class value from payload node, you can use
/dataEnvelope/payload[#class]/#class
or just
/dataEnvelope/payload/#class
At first, your two XML files are out-of-sync - one references envelope and the other references dataEnvelope. So exchange one for the other, if necessary.
So, to get the attribute value of payload, you can use an XPath expression like this which uses a child's attribute value to be more specific:
/envelope/payload[fizz[#buzz='3']]/#class
Output is:
vendor
If the document element can/will change, then you can keep the XPath more generic and select the value of the class attribute from the payload element that is a child of any element:
/*/payload/#class
If you know that it will always be a child of envelope, then this would be more specific(but the above would still work):
/envelope/payload/#class
I'm working on creating a custom report report page in CQ5. I've got my reportbase and columnbase components set up correctly, by following the steps listed here. I am able to, for instance, pick up all the templates that are available, by setting the property nodeTypes to cq:Template
I want to add a constraint to it, say for example pick up templates whose jcr:title is foo. I created a node under querybuilder called propertyConstraints and added my constraints in the form of nodes below it, as describedhere. However, this does not work for me at all.
What is the correct way to add constraints to the querybuildernode? Has anyone tried this?
Also, once I get this working correctly, can I extend this example to return pages of a specific template?
Have you looked into the QueryBuilder API? Adobe's documentation discusses how to match 1 or more property values.
Create a node propertyConstraints under queryBuilder of type nt:unstructured
create another node under propertyConstraints with any name.
Add properties to this node :
name String jcr:title
value String foo
I created an ALV TREE report, using cl_gui_alv_tree, that has 3 levels. I'm also implementing an event handler for when he double clicks a node.
My problem is that I want to take some actions only when he double clicks a node that is a root node. The event 'node_double_click' gives a node_key, but that's the index of the displayed table. How could I achieve this?
The node ID is not an index, it's the ID you assigned to the node when adding it to the tree.
If possible, I'd suggest switching to CL_SALV_TREE - not only because it is documented
and supported by SAP, but also because it comes with some query methods that are quite handy. These methods are documented as well. You can use, for example, GET_NODE to retrieve a node by its ID and then use GET_PARENT to check whether the node in question is a top-level node or has a parent node it is attached to.
I created a pattern for myself, which i am using.
lv_parent1 = node_key.
while lv_parent1 ne go_Main_tree->C_VIRTUAL_ROOT_NODE.
CALL METHOD go_main_tree->get_parent
EXPORTING
i_node_key = lv_parent1
IMPORTING
e_parent_node_key = lv_parent1.
lv_hierlevel = lv_hierlevel + 1 .
ENDWHILE.
if lv_hierlevel > 2.
“ do what You want to do

I am new to RGL. I want to show a graph of all parent and children type relations.
I have written the following code.
My code is as:
require 'rgl/adjacency'
require 'rgl/dot'
input_arr = [1,2,2,3,2,4,4,5,6,4,1,6]
We need to give input as following to generate graph.
dg=RGL::DirectedAdjacencyGraph[1,2,2,3,2,4,4,5,6,4,1,6]
dg.write_to_graphic_file('jpg')
But I want to give the array dynamically, ie I want to pass input_arr. But it is not working.
can anybody explain how to go?
Eventually I could solve my issue.
I have written like the folowing:
I have processed my main_arr variable something like this.
main_arr=[[1,2],[2,3],[2,4],[4,5],[6,4],[1,6]]
dg=RGL::DirectedAdjacencyGraph[]
main_arr.each do |ma|
dg.add_edge ma[0],ma[1]
end
Now it is working fine.
Now I can pass any dynamic values to generate graph.
I'm using following spec with MiniTest::Spec and Capybara:
find_field('Email').must_have_css('[autofocus]')
to check if the field called 'Email' has the autofocus attribute. The doc says following:
has_css?(path, options = {})
Checks if a given CSS selector is on the page or current node.
As far as I understand, field 'Email' is a node, so calling must_have_css should definitely work! What I'm doing wrong?
Got an answer by Jonas Nicklas:
No, it shouldn't work. has_css? will check if any of the descendants
of the element match the given CSS. It will not check the element
itself. Since the autofocus property is likely on the email field
itself, has_css? will always return false in this case.
You might try:
find_field('Email')[:autofocus].should be_present
this can also be done with XPath, but I can't recall the syntax off
the top of my head.
My solution:
find_field('Email')[:autofocus].must_equal('autofocus')
Off top of my head. Can you use has_selector?(). Using Rspec wit Capy:
page.should have_selector('email', autofocus: true)
Also check Capybara matchers http://rubydoc.info/github/jnicklas/capybara/master/Capybara/Node/Matchers
I've not used MiniTest before but your syntax for checking for the attribute looks correct.
My concern would be with your use of find_field. The docs say:
Find a form field on the page. The field can be found by its name, id or label text.
It looks like you are trying to find the field based on the label. If so I would check that you have the for attribute on it and and that it has the correct id of the form field you are looking for. To rule out this being the issue you could temporarily slap an id your form field and look for that explicitly.
