Nejdriv vsem diky za rady...a mam dalsi otazku:
reseni: mam xml soubor a chci do nej pridat element(additionalData)...tak
aby byl pridan do kazdeho "data"
Kdyz mam xml soubor, ktery obsahuje(zkraceno)(vzor1.xml):
<neco>
<tagA>Ahoj Svete</tagA>
</neco>
<data>
<host>localhost</host>
<user>root</user>
</data>
potom mam program:
from xml.dom import minidom
def findTextNodes(nodeList, tagname, new):
for subnode in nodeList:
if subnode.nodeType == subnode.ELEMENT_NODE:
if (subnode.nodeType == subnode.ELEMENT_NODE and
subnode.tagName ==
tagname):
new = doc.createElement(new)
subnode.appendChild(new)
new.appendChild(doc.createTextNode("tento text
doplnen"))
findTextNodes(subnode.childNodes, tagname, new)
doc = minidom.parse('vzor1.xml')
findTextNodes(doc.childNodes, "data", "AdditionalData")
print doc.toxml()
A vsechno funguje bez problemu... sice mi to tam prida podivne(ze neudela
ten tabulator a na konci prechod na dalsi radek)
vysledek:
<neco>
<tagA>Ahoj Svete</tagA>
</neco>
<data>
<host>localhost</host>
<user>root</user>
<AdditionalData>tento text doplnen</AdditionalData></data>
ALE kdyz zmenim XML na:
<neco>
<tagA>Ahoj Svete</tagA>
</neco>
<data>
<host>localhost</host>
<user>root</user>
</data>
<data>
<host>local</host>
<user>toor</user>
</data>
tak uz pridavani nefunguje a hodi to opravdu zvlastni chybu:
Traceback (most recent call last):
File "together1.py", line 26, in ?
print doc.toxml()
File "/home/pleva/lib/_xmlplus/dom/minidom.py", line 47, in toxml

File "/home/pleva/lib/_xmlplus/dom/minidom.py", line 59, in toprettyxml

File "/home/pleva/lib/_xmlplus/dom/minidom.py", line 808, in writexml
writer.write(indent+"<" + self.tagName)
TypeError: cannot concatenate 'str' and 'instance' objects
-z cehoz jsem pochopil, ze nemuze spojit tag, ale vubec nevim kvuli cemu...
Tak predem moc dik za rady, uz to vidim, ze to bude zas naka banalita :))
