Im automaticaly generating the version with starts-with() ends-with() and now I was wandering if i should add an extra case if they have the same text to compare than it should replace it with an =
Is there a difference between //*[starts-with(., 'hello') and ends-with(., 'hello')] and //*[.='hello']?
It's not the same, there can be stuff in between. For example hello hello.

Have a many entries in an xml file and have xpath with condition:
/XMLReport/Report/PreflightResult/PreflightResultEntry[
#type = 'Check' and #level = 'warning']/PreflightResultEntryMessage/Message/text()
The output is:
onetwothreefour... and more
I need separation
'---' one---two---three---four
or
[enter]
one
two
three
four
Its possible ?
Why you bound XPath expression inside single quote ':
Use this:
string-join(/XMLReport/Report/PreflightResult/PreflightResultEntry[#type = 'Check' and #level = 'warning']/PreflightResultEntryMessage/Message/text(), '---')
Your XPath expression is actually returning a set of text nodes. The way these are displayed depends on the calling application (which you haven't told us anything about). I think your options are (a) change the way the calling application displays the result, or (b) if you're using XPath 2.0+, use the string-join() function to return the result as a string, formatted any way you like within the XPath expression itself.
Let me start with I'm not a programmer by trade, but I'm learning the best I can. I'm trying to build a template to take the result of one FreeMarker interpolation result and use that as a variable for another. I hope I'm using the terms correctly.
For example, I want the result of (entity.customer.organization.name) to be used in:
${blurb["organizationXXXAttire"]!}
Where XXX is the result of (entity.customer.organization.name)
If it was just a blurb with out a variable company name it would look like:
${blurb["organizationCompanyAttire"]!}
I thought the following would work but it did not:
<#assign organization = (entity.customer.organization.name)>
${blurb["organization<#organization?interpret>Attire"]!}
Thanks in advance for any suggestions.
It's simply ${blurb["organization${entity.customer.organization.name}Attire"]!}.
?interpret is only needed if you have a string that contains a piece of template. Besides you can't call directives (<#...>, <#...>) inside an expression.
I have a textarea control with an Id that goes something like this:
<textarea id="NewTextArea~~51887~~1" rows="2"/>
And the xpath that has worked before has been
//textarea[#id, "NewTextArea~~51887~~1"]
But now the '51887' portion of the id is become diverse (changing every time) so I need to select the NewtextArea~~*~~1 element without actually specifying the number. Is there a way I can wildcard part of the string so that it will match a particular pattern? I tried using starts-with and ends-with but couldn't get it to work:
//textarea[starts-with(#id, 'NewTextArea~~') and ends-with(#name, '~~1')]
Bare in mind there are other fields with the difference being the number on the end.
Any advice or guidance would be greatly appreciated :)
I tried using starts-with and ends-with but couldn't get it to work:
//textarea[starts-with(#id, 'NewTextArea~~') and ends-with(#name, '~~1')]
ends-with() is available as a standard function only in XPath 2.0 and you seem to be using XPath 1.0.
Use:
//textarea
[starts-with(#id, 'NewTextArea~~')
and
substring(#id, string-length(#id) - 2) = '~~1'
]
Explanation:
See the answer to this question, for how to implement ends-with() in XPath 1.0:

I have a general idea of how I can do this, but can't pinpoint how exactly to get it done. I am sure it can be done with a regex of some sort. Wondering if anyone here can point me in the right direction.
If I have a string of html such as this
some_html = '<div><b>This is some BOLD text</b></div>'
I want to to divide it into logical pieces, and then put those pieces into an array so I end with a result like this
html_array = ["<div>", "<b>", "This is some BOLD text", "</b>","</div>" ]
Rather than use regex I'd use the nokogiri gem (a gem for parsing html written by Aaron Patterson - contributor to Rails and Ruby). Here's a sample of how to use it:
html_doc = Nokogiri::HTML("<html><body><h1>Mr. Belvedere Fan Club</h1></body></html>")
You can then call html_doc.children to get a nodeset and work your way from there
html_doc.children # returns a nodeset
Use an HTML parser, for instance, Nokogiri. Using SAX you can add tags/elements to the array as events are triggered.
It's not a good idea to try to regex HTML, unless you're planning to treat only a small determined subset of it.
some_html.split(/(<[^>]*>)/).reject{|x| '' == x}
I'm using Nokogiri to parse a large XML file. Say I've got the following structure:
<menagerie>
<penguin>Pablo</penguin>
<penguin>Mortimer</penguin>
<bull>Ferdinand</bull>
<aardvark>James Cornelius Madison Humphrey Zophar Handlebrush III</aardvark>
</menagerie>
I can count the non-penguins like this:
xml.xpath('//menagerie//*[not(penguin)]').length // 2
But how do I get a list of the tags, like this? (The exact format isn't important; I just want to visually scan the non-penguins.)
bull
aardvark
Update
This gave me the list I wanted - thanks Oded and TMN and delnan!
xml.xpath('//menageries/*[not(penguin)]').each do |node|
puts node.name()
end
You can use the name() or local-name() XPath function.
See the examples on zvon.
I know it's a bit outdated but you should do: xml.xpath('//meagerie/*[not(penguin)]/name()') as the expression. Note the slash, not the dot. This is how you call methods on the current node in XPath.
