I have the following Xml structure; Payment/Line which has amongst its element a IsFeePayment and a IsServiceProduct elements of type bool.
<Payment>
<Line>
<IsFeePayment>true</IsFeePayment>
<ISServiceProduct>true</IsServiceProduct>
</Line>
</Payment>
i want an xpath statement that returns 'true' when both of these are are they are, true.
if either one is false, i want the xpath statement to return 'false'
THe xpath below is almost there, it returns the line when both are true.
/[local-name()='Payment']/[local-name()='Line'][*[local-name()='IsFeePayment'][text()='true'] and *[local-name()='IsServiceProduct'][text()='true']]
how do i just get a simple bool out instead of the whole element?
You can simplify the xpath to
boolean(//Payment/Line[IsFeePayment='true' and IsServiceProduct='true'])
simply adding a boolean() around the xpath expression i already had fixes the problem blush
so ...
boolean(/[local-name()='Payment']/[local-name()='Line'][*[local-name()='IsFeePayment'][text()='true'] and *[local-name()='IsServiceProduct'][text()='true']])

Spark SQL (Databricks) function xpath ignores empty tags in XML. For example for below XML XPATH returns array ["ABC"]. We need it as ["ABC", NULL or empty string] because when we use this along with posexplode_outer, omitting null in XPATH will cause incorrect association.
Is there any option in XPATH to retain nulls? I did not find any detailed documentation for this.
SELECT xpath("<PARTY>
<PARTY_EVENT>
<EVENTTYPE>VISITED</EVENTTYPE>
<LOCATION>ABC</LOCATION>
</PARTY_EVENT>
<PARTY_EVENT>
<EVENTTYPE>VISITED</EVENTTYPE>
<LOCATION />
</PARTY_EVENT>
</PARTY>"
, '/PARTY/PARTY_EVENT/LOCATION/text()')
Add the nodes not containing any text by using [not(text())] selector:
(/PARTY/PARTY_EVENT/LOCATION|/PARTY/PARTY_EVENT/LOCATION[not(text())])/text()
From my xml, I can get this :
<home>
<creditors>
<count>2</count>
</creditors>
</home>
OR even this :
<home>
<creditors>
<moreThan>2</moreThan>
</creditors>
</home>
Which xpath expression can I use to get "<count>2</count>" instead of getting only "2" OR to get "<moreThan>2</moreThan>" instead of getting "2" ?
This XPath,
//creditors/count
will select all count child elements of all creditors elements in the XML document.
Update per OP's request in comments for a single XPath that selects both count and moreThan elements:
This XPath,
//creditors/*[self::count or self::moreThan]
will select all count or moreThan child elements of all creditors elements in the XML document.
Assuming that your xpath expression is OK, you just need to convert the element to string:
doc.xpath("home/creditors/*").to_s
=> "<count>2</count>"
Please check with queries returning more than one element, to make sure that it's desired behaviour.
I am having difficulty figuring out an XPath query that would allow me to return nodes based on the value of the Program attribute in the example below. For example, I would like to be able to search all nodes for a value of the Program attribute = "011.pas". I tried /Items/*[Program="012.pas"] and also /Items/Item*[Program="01.pas"] but neither works. What is the correct expression?
<Items>
<Item0 Program="01.pas"></Item0>
<Item1 Program="011.pas"></Item1>
</Items>
The attribute is selected with #Program, the child elements of the Items element with /Items/*, so you want /Items/*[#Program = '011.pas'].
Try this :
/items/*[#Program='011.pas']
In case below two elements do not show in same time
<a title='a' />
<b title='b' />
I want to check if one of them can show
does xpath support the 'or' function? I just want to write in one line:
//a[#title='a'] or .. #title='b' ??
XPath Operators
Select either matching nodes (your case here):
//a[#title='a'] | //b[#title='b']
Select one element with either matching attributes
//a[#title='a' or #title='b']
If you want to match either <a/> elements with #title='a' attribute or <b/> elements with #title='b' attribute, you can also match all elements and perform a test on their name:
//*[local-name(.) = 'a' and #title='a' or local-name(.) = 'b' and #title='b']
I have the plenty of links like this:
<b>Edit issue >></b>
Trying to extract the href' content I use Xpath expression:
//a[contains(#href,'/edit_flat')]
but it returns me null. What am I doing wrong ?
//a[contains(#href,'/edit_flat')] selects a elements anywhere in the document tree that have an href attribute containing the '/edit_flat' string.
These matching elements do have this very "href" attribute, but the XPath expression you are using returns "only" the a elements, if there are any.
To actually return the matching elements' attribute's values, you need an extra step, with / and #href. So what you want is:
//a[contains(#href,'/edit_flat')]/#href
Suggestion:
What you really want is probably to select links which href begin with the substring "/edit_flat", so it's safer to use:
.//a[starts-with(#href,'/edit_flat')]/#href
