I'm creating a SonarCube rule that checks all sql-files. This rule should check if all keywords like SELECT, INSERT etc are written in uppercase.
IF NOT EXISTS(select * FROM sys.columns Where Name = N'idUser' AND Object_ID = Object_ID(N'lp_t_Rpt_Order'))
ALTER TABLE lp_t_Rpt_Order
ADD idUser INT NULL
In this case the xpath query should match 'select' and 'Where' which do not follow the rule of being all UPPERCASE.
I have a list of all keywords so I find them, but know I want to know how I have to write or expand the xpath expression to only match words containing lowercase letters.
/COMPILATION_UNIT//*[#tokenValue = 'SELECT' or #tokenValue = 'INSERT' or #tokenValue = 'WHERE']
This is a shortend version of my xpath expression. If I included all key words the query would be way to long to display on this site.
This is how the Abstract Syntax Tree looks like.

I have a feed here. I'm trying to create an XPath expression that returns items that have a category equal to Bananas. Due to the limitations in my XML parser, I can't use namespaces directly to select items.
The expression /rss/channel/item//*[name()='itunes:category'] returns this:
Element='<itunes:category
xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd"
text="Apples"/>'
Element='<itunes:category
xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd"
text="Bananas"/>'
...
And /rss/channel/item//*[name()='itunes:category']/#text returns this:
Attribute='text=Apples'
Attribute='text=Bananas'
...
But I can't figure out how to limit the response to just a single category (e.g., Bananas)?
I want some kind of expression like this:
/rss/channel/item//*[name()='itunes:category' and contains(., 'Bananas')]
But this doesn't work. It's not syntactically valid. What would be the right XPath expression syntax to just return Bananas?
Do you just mean to filter by attributes of item child, but still return item node?
/rss/channel/item/*[name()='itunes:category' and contains(#text,'Apples')]/parent::item
or simplier
/rss/channel/item[*[name()='itunes:category' and #text='Apples']]
I used Apples in example because using your example xml file there is 0 results for Bananas.
I'm working on Xpath/Xquery to return values of multiple child nodes based on a sibling node value in a single query. My XML looks like this
<FilterResults>
<FilterResult>
<ID>535</ID>
<Analysis>
<Name>ZZZZ</Name>
<Identifier>asdfg</Identifier>
<Result>High</Result>
<Score>0</Score>
</Analysis>
<Analysis>
<Name>XXXX</Name>
<Identifier>qwerty</Identifier>
<Result>Medium</Result>
<Score>0</Score>
</Analysis>
</FilterResult>
<FilterResult>
<ID>745</ID>
<Analysis>
<Name>XXXX</Name>
<Identifier>xyz</Identifier>
<Result>Critical</Result>
<Score>0</Score>
</Analysis>
<Analysis>
<Name>YYYY</Name>
<Identifier>qwerty</Identifier>
<Result>Medium</Result>
<Score>0</Score>
</Analysis>
</FilterResult>
</FilterResults>
I need to get values of Score and Identifier based on Name value. I'm currently trying with below query but not working as desired
fn:string-join((
for $Identifier in fn:distinct-values(FilterResults/FilterResult/Analysis[Name="XXXX"])
return fn:string-join((//Identifier,//Score),'-')),',')
The output i'm looking for is this
qwerty-0,xyz-0
Your question suggests some fundamental misunderstandings about XQuery, generally. It's hard to explain everything in a single answer, but 1) that is not how distinct-values works (it returns string values, not nodes), and 2) the double slash selections in your return statement are returning everything because they are not constrained by anything. The XPath you use inside the distinct-values call is very close, however.
Instead of calling distinct-values, you can assign the Analysis results of that XPath to a variable, iterate over them, and generate concatenated strings. Then use string-join to comma separate the full sequence. Note that in the return statement, the variable $a is used to concat only one pair of values at a time.
string-join(
let $analyses := FilterResults/FilterResult/Analysis[Name="XXXX"]
for $a in $analyses
return $a/concat(Identifier, '-', Score),
',')
=> qwerty-0,xyz-0
I have to provide the ref attribute value in an xf:select1. I need to select names of properties only if they are present in the supportedProperties instance which can be done with the following:
<xf:select1
ref="
instance('properties')/property[
name = instance('supportedProperties')/property/name
]/name">
However, the problem is that supportedProperties can contain names which are in capital letters. Assuming we cannot change the instance, is there a way we can do a case sensitive comparison?
Tried to use the lower-case() XPath function as follows but it didn't work:
<xf:select1
ref="
instance('properties')/property[
name = instance('supportedProperties')/property/name
]/lower-case(name)">
Assuming you are using XPath 2, you can write:
<xf:select1
ref="
instance('properties')/property[
name = instance('supportedProperties')/property/name/lower-case(.)
]/name">
What this does is that the lower-case(.) function applies to all elements in the sequence returned by instance('supportedProperties')/property/name.
You can also write it:
<xf:select1
ref="
instance('properties')/property[
name = (
for $name in instance('supportedProperties')/property/name
return lower-case($name)
)
]/name">
I'm trying to get the array of authors of this website:
http://www.intechopen.com/books/latest/1/list
with this xpath:
response.xpath("//div[#id='sizer']/div[#id='content']/div[#class='grid']/div[#class='main-content']/div[#id='tc']/div/ul[#class='book-listing entity-listing']/li/dl/dd[#class='meta']/text()[count(preceding-sibling::br) = 0]").extract()
but i want only the names, without the "editor", how can I do it?
After selecting the text, use the regular expression function re() with a capture group in order to exclude the text you do not want:
response.xpath("//div[#id='sizer']/div[#id='content']/div[#class='grid']/div[#class='main-content']/div[#id='tc']/div/ul[#class='book-listing entity-listing']/li/dl/dd[#class='meta']/text()[count(preceding-sibling::br) = 0]")
.re(r'Editor\s*(.*)')
I would like to select a attribute and the text() value of a node in one query, e.g. I have
<Tag1 #myattr='test'>MyText</Tag1>
and I am interested in getting "test" and "MyText" with one query.
The obvious
//Tag1/#myattr | //Tag1/text()
fails due to the fact, that Unions are only allowed over node-sets.
Any ideas?
I think, given XPath 2.0, you want a sequence of string values which you get with //Tag1/(#myattr, .)/string(). If you want a single string then use //Tag1/string-join((#myattr, .), ' ').
BTW, your path //Tag1/#myattr | //Tag1/text() would select a sequence containing an attribute value and a text node. I don't see how that would fail.
