xpath nil test

2. Now we want to select:

some list itemv1

Print the value of the table item: some list itemv1

by using :{{ xml.text(page.xml, "//td[@id='somefield']") }}

Now we have a p paragraph in the table

some list itemv2

Print the value of the table item: some list itemv2

by using :{{ xml.text(page.xml, "//td[@id='somefield2']") }}

This doesn't work because the xpath contains multiple elements...

Print the value of the table item:[ " " ]

by using :{{ xml.list(page.xml, "//td[@id='somefield2']") }}

We have to print them all:

Print the value of the table item:[ "some list itemv2" ]

by using :{{ xml.list(page.xml, "//td[@id='somefield2']//*") }}

But if we use this query on the original data element it doesn't work

Print the value of the table item:[]

by using :{{ xml.list(page.xml, "//td[@id='somefield1']//*") }}

So we use the descendant-or-self axis to include the parentnode

Print the value of the table item:

met td voorop:[ "\u00a0 some list itemv1", " ", "some list itemv2" ]

met td 2 :[ "\u00a0 some list itemv1", " ", "some list itemv2", " " ]

by using met td voorop:{{ xml.list(page.xml, "//td/descendant-or-self::*") }}
met td 2 :{{ xml.list(page.xml, "//td/descendant-or-self::text()") }}

But this doesn't work?! because nil values or empty strings are returned

Filtering nil or empty strings

met td voorop:[ "\u00a0 some list itemv1", " ", "some list itemv2" ]

met td 2 :[ "\u00a0 some list itemv1", "some list itemv2" ]

met td voorop:{{ xml.list(page.xml, "//td/descendant-or-self::*[normalize-space(.)]")  }}

met td 2 :{{ xml.list(page.xml, "//td[(contains(@id, 'some'))]/descendant-or-self::text()[normalize-space(.)]") }}

Viewed : 74

Now return attrib values: (work in progress)

[ "somefield", "somefield2" ]

Now we want to select:

-all attribute values from the a's in a td

-all text values from all none a text

Data:

Jan

de tekst www.yahoo.com
Piet

Sinterklaas

De querys:

[ "de tekst www.yahoo.com" ]

[ "/http://www.yahoo.com/Een_blanco_spatie" ]

De weergave van de queries

{{ xml.list(page.xml, "//div[@id='test']/a") }}
{{ xml.list(page.xml, "//div[@id='test']/a/@href") }}

De ontkennende queries

[ "\n", "Jan", "Sinterklaas" ]

[ "Jan", "\nPiet\n", "Sinterklaas" ]

{{ xml.text(page.xml, "//div[@id='test']/[not(a)]", _, true) }}
