PHP Development article within the chain, a problem with the replacement rule
Do the inner chain method, can think of is to replace the set of good inner chain words, such as the "Spring Festival holiday" replaced with "Spring Festival Holiday", and so on, this way to
But the fact may not be so simple, because the article is often sent with HTML tags, such as may be " Spring Festival
Holiday"In this form, how to replace it?"
Thought maybe there might be a concentration below.
"Spring Festival Holiday"This is to be replaced, into such a" spring festival Holiday”
This direct form of "Spring Festival Holiday" does not replace
“ Spring FestivalHoliday "This type of label is not replaced
"Spring Festival Holiday" This part of the word has a link does not replace
。。。 Maybe there's a situation for him.
In the language description, "Every word is replaced without a link, the link may be a direct link may also be a tag link"
Then replace it with "multiple word breakers within the nearest parent node, replacing the new form with the newly Added link".
