Question:
for example, we have this xml:
<p>[TAG] <span>foo 1</span> <span>foo 2</span> [/TAG] <span>bar 1</span> <span>bar 2</span> </p> how can i detect <span>-tags between words [TAG] and [/TAG] ("foo 1" and "foo 2" in this case)?
UPD. for example i need to change nodeValue of each span between [TAG] and [/TAG]
Solution:1
Assuming that you only have one set of [TAG]..[/TAG] per node (as in, if your document has two sets they're within separate <p> elements or whatever), and that they're always siblings:
You can use preceding-sibling and following-sibling to select only elements which are preceded by a [TAG] text node and followed by a [/TAG] text node:
//span[preceding-sibling::text()[normalize-space(.) = "[TAG]"]][following-sibling::text()[normalize-space(.) = "[/TAG]"]] A full PHP example:
$doc = new DOMDocument(); $doc->loadHTMLFile('test.xml'); $xpath = new DOMXPath($doc); foreach ($xpath->query('//span[preceding-sibling::text()[normalize-space(.) = "[TAG]"]][following-sibling::text()[normalize-space(.) = "[/TAG]"]]') as $el) { $el->nodeValue = 'Changed!'; } echo $doc->saveXML(); Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
