when i use birt, my data with sql query are contains many html tags,like
[quote][/quote]
[img][/img]
,i prefer to replace it with regexp,but i can't successful,
i print
<VALUE-OF>row["content"].replace(/\[\/?[a-z]*\W*\w*]/gi, "")</VALUE-OF>
in 【edit text item】,
also i wrote 【data banding】 in expression with
dataSetRow["content"].replace(new RegExp("/[\[]\/?\W*]/g","ig"),"")
it failed,i have no idea
I use the wrong method ,the right is replaceAll()

I want to extract all the functions listed inside the table in the below link : python functions list
I have tried using the chrome developers console to get the exact xpath to be used in the file spider.py as below:
$x('//*[#id="built-in-functions"]/table[1]/tbody//a/#href')
but this returns a list of all href's ( which I think what the xpath expression refers to).
I need to extract the text from here I believe but appending /text() to the above xpath return nothing. Can someone please help me to extract the function names from the table.
I think this should do the trick
response.css('.docutils .reference .pre::text').extract()
a non-exact xpath equivalent of it (but that also works in this case) would be:
response.xpath('//table[contains(#class, "docutils")]//*[contains(#class, "reference")]//*[contains(#class, "pre")]/text()').extract()
Try this:
for td in response.css("#built-in-functions > table:nth-child(4) td"):
td.css("span.pre::text").extract_first()
I've been trying to use the following X-Path within Google-Sheets with the =ImportXML function
=importXml("http://www.managetickets.com/morecApp/ticketSearchAndStatusTicketList.jsp?msgCount=23&outputEmail=&db=nd", "/table[2]/tbody/tr#[td]")
But no matter what minor adjustments I try I continually get "#N/A" with a hover-text box that says "imported content is empty".
I know it's a valid x-path, I've cross verified it with 'X-Path Helper Wizard' chrome-extension.
Any ideas what I'm doing wrong!?
No, actually it's not a valid XPath. Note that # used to select an attributes e.g. #class, #id, etc. Also it's a bad idea to use tbody tag in your expressions as this tag is not always present in initial source code
So if you want to match table rows which contain cells from second table, you can use
/table[2]//tr[td]
I want to click on 'Select' where preceding block contains text, "Byron Test 20150904". This text is dynamic
After trial and error i find the answer
//div[#id='itOverview']/div[.//a[contains(text(),'Byron Test 20150904')]]/div/div[3]/div[2]/a
I have two cq page and I want to retrive these two using jcr:title property using XPATH. The below query is working fine for single.
/jcr:root/content/test//element(*, cq:Page)[((jcr:like(jcr:content/#jcr:title, dell)))]
But I want to excuate it for multiple items. I have tried with following option but it is not working
/jcr:root/content/test//element(*, cq:Page)[((jcr:like(jcr:content/#jcr:title, [dell,samusng])))]
Could anyone help me to write xpath query?
As rakhi4110 already mentioned in the comment, you can combine multiple where clauses with an or just like in SQL. Though I think you either want exact matches or use jcr:containts instead of jcr:like.
Exact match:
/jcr:root/content/test//element(*, cq:Page) [jcr:content/#jcr:title='dell' or jcr:content/#jcr:title='samsung']
Contains:
/jcr:root/content/test//element(*, cq:Page) [jcr:contains(jcr:content/#jcr:title, 'dell') or jcr:contains(jcr:content/#jcr:title, 'samsung')]
Or if you really want to use jcr:like which, as in SQL, uses % for wildcard:
/jcr:root/content/test//element(*, cq:Page) [jcr:like(jcr:content/#jcr:title, '%dell%') or jcr:like(jcr:content/#jcr:title, '%samsung%')]
My current issue is to find HTML-Tags inside of property values. I thought it would be easy to search with a query like /jcr:root/content/xgermany//*[jcr:contains(., '<strong>')] order by #jcr:score
It looks like there is a problem with the chars < and > because this query finds everything which has strong in it's property. It finds <strong>Some Text</strong> but also This is a strong man.
Also the Query Builder API didn't helped me.
Is there a possibility to solve it with a XPath or SQL Query or do I have to iterate through the whole content?
I don't fully understand why it finds This is a strong man as a result for '<strong>', but it sounds like the unexpected behavior comes from the "simple search-engine syntax" for the second argument to jcr:contains(). Apparently the < > are just being ignored as "meaningless" punctuation.
You could try quoting the search term:
/jcr:root/content/xgermany//*[jcr:contains(., '"<strong>"')]
though you may have to tweak that if your whole XPath expression is enclosed in double quotes.
Of course this will not be very robust even if it works, since you're trying to find HTML elements by searching for fixed strings, instead of actually parsing the HTML.
If you have an specific jcr:primaryType and the targeted properties you can do something like this
select * from nt:unstructured where text like '%<strong>%'
I tested it , but you need to know the properties you are intererested in.
This is jcr-sql syntax
Start using predicates like a champ this way all of this will make sense to you!
HTML Encode <strong>
HTML Decimal <strong>
Query builder is your friend:
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%3Cstrong%3E%25
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have a go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%26lt%3Bstrong%26gt%3B%25
XPath:
/jcr:root/content/geometrixx//element(*, nt:unstructured)
[
jcr:like(#text, '%<strong>%')
]
SQL2 (already covered... NASTY YUK..)
SELECT * FROM [nt:unstructured] AS s WHERE ISDESCENDANTNODE([/content/geometrixx]) and text like '%<strong>%'
Although I'm sure it's entirely possible with a string of predicates, it's possibly heading down the wrong route. Ideally it would be better to parse the HTML when it is stored or published.
The required information would be stored on simple properties on the node in question. The query will then be a lot simpler with just a property = value query, than lots of overly complex query syntax.
It will probably be faster too.
So if you read in your HTML with something like HTMLClient and then parse it with a OSGI service, that can accurately save these properties for you. Every time the HTML is changed the process would update these properties as necessary. Just some thoughts if your SQL is getting too much.
